Actually, I can't help thinking "Share violation reading file winword.exe - this file is in use by another program. Windows will reboot now in order to free the file winword.exe for your usage [OK] "
It's a legit comment you mod-nazis... They plainly push the fact that you can play head-to-head games if you get a dual-port VGA card... It doesn't do much good to tout that as a selling point if the games play like shit!
Depends on the card, the processor, and the game, I'd guess. You'd basically be doubling the load on both the video card and the processor. I can see Quake3 running just fine regardless, but a newer game might have some problems. I doubt that they're going for the hardcore gamer demographic with this concept, though.
Windows XP is truly multi-user. I'm sure there's a little setting in there for multiple monitors. As is, multiple people can all be logged in at the same time, all running their own programs.
I have Win XP Pro, and, while 2 users can be logged in at one time (one at the console, the other over a network), they both cannot be working at the same time.
I don't call that "truly multi-user."
By contrast, my Mac, running OS X, is truly multi-user: I can connect to it over the network while someone else is at the console, and we both can do stuff.
But that's just how Microsoft chose to license it (XP workstation). There is nothing inherent in the OS, that prevents them from working in parallel. In fact, NT Servers (XP and 2000) allow multiple people to login. I'm using Remote Desktop [rdesktop.org] right now to access one from my FreeBSD box.
Also, rumors are, the limit on the number of simultamious users can be increased by careful editing of the registry, but I can not find the link right now...
bhtooefr is correct. There can be only one person connected whether it be at the console or via RDP. Logging on via RDP disconnects everybody else and connects to an existing desktop if that user has already logged in. Logging on at the console will then disconnect that remote user, and connect to the same session if it is the same username.
I wish there were a way to hack XP's terminal services to allow multiple concurrent logons.
VNC can be configured under Linux to display an existing desktop, not just one of it's own virtual desktops. This is how KDE implements desktop sharing.
meaning the MoBo is actually siamese twins sharing non-critical chips (err.. organs).
I predict, in the very near future, a blockbuster Hollywood buddy movie about one of these conjoined mobos: Stuck on BSOD.. Starring Matt Damon as the Chipset and Greg Kinnear as the Floppy Drive. Bound to make a mint, no chance that it will bomb...
in this case, yes, they are quite non-critical for the purposes of dual-user/single-box.
If the industry supports this little abomination, then perhaps in the near future we will see some maturation of true, multiple concurrent local terminal sessions supporting multiple users in the modern OS's. A propietary MoBo to allow this function will not be a savings over two low-end mobos, because of lower production, lower demand, limited expandability/upgradability.
Looks like as noted above that this is a softwear & XP trick, and not actually directly related their pc in particular. They specify that it needs their proprietary softwear, a 2 head VGA card and a mouse and keyboard splitter. Id bet they rout the input of 1 set of devices to each user and controll XP login with it.

That problem is easily answered when considering 1 or 2 computers run off one interface (VNC, TS, telnet, ssh). But the problem comes when one wants to manage their whole lab infrastructure or every computer in their home from one interface. Windows 2003 comes with a neat little MMC snapin called "Remote Desktops" that lets you manage all of your TS sessions. The problem with that is that there is one process for each computer, and if you can imagine, 100-1000 mstsc.exe processes can consume quite a bit of

Both of these solutions require two cpus and two monitors, but they work pretty well for this.
I wonder how licensing will work for software installed on such a computer.
Will software makers insist that multiple licenses be bought for software that will be used by two users simultaneously?
And speaking of things being equal, I feel a Grammar Raid coming on...
"Magic Twin looks like a pretty unique solution..." the article says. Why do people insist on qualifying the word unique? Something is either unique or it isn't. An object cannot be "somewhat unique" or "almost totally unique." The word means one of a kind, and without equal. Something either has equals or it doesn't.

And my addendum is the worstest joke on the subject, ever.
There are already a few misguided posts on the matter so hopefully, I can clear this up for you.
Microsoft and many other software makers already address this licensing issue. On this machine Microsoft requires either two licenses for Windows or one Windows license and a Terminal Server Client Access license. For MS Office a license is required for each per seat instance. SO, two users in Word requires two licenses.
This same licensing system is also required by many/most other commercial vendors. Anyone familiar with Terminal services or Citrix should be familiar with this licensing model. If they aren't Microsoft will enjoy speaking with them.
Ok, so it's per-seat. Is Visual C++ per seat, and what implications does this have for extreme programming?
Visual C++ is per seat. Extreme Programming is not alright. Extreme Programmers are pirates. They are an evil group of people who have figured out a way to get around our DRM. But it will not be tolerated. We are hard at work, finding a way to stop them, and force the people who leech off another user's terminal to pay up. Our current strategy is to make maximum font size in Windows 6 points. Then a

(other than Microsoft) will care.
Not a troll or flamebait - Really, how many
home users actually went out and bought
Windows or Office? For a business, a few
hundred bucks might not mean much (particularly
in comparison with getting caught running an
unlicensed app). For a home user, many people
balk at even paying $50 for their tax
software, nevermind something as mundane as
a word processor and spreadsheet (and the
rest, that I have yet to see anyone use
outside a work environment).
People get Windows with their machines. They
get Office from a friend or borrow the install
CD from work. Legality simply doesn't matter,
end of story.
Or, for an already-common analogy, how many
people paid extra fees to use on a dual-CPU
box (most commercial software includes provisions
limiting its use to on a per-CPU basis as well)?
Answer? No one. Even businesses usually
overlook that one, for "mere" duals.
Except that you are only installing it once, and then time slicing between it. I could see this a s a novel way to cut back on our Microsoft Licensing fee's For example our accounting department doesn't need a fast computer, but if we could rreduce the number of pc's from 100 to fifty, thats a heck of alot of costs savings for a mid size company.
50 license for windows instead of 100
50 license of office instead of 100
50 Server CAL's instead of 100
Hmm, how much do these cost?
That's pretty much old terminology. Currently it's per user or per computer. Read the license options for each product you plan on installing and figure out what method is the least expensive.
2 users can browse the internet, send and receive email at the same time
2 users can access all software installed on the PC at the same time (Excel, Word, PowerPoint, Data Base, games, etc.)
2 users can play games against each other with a dual-port VGA card
I know many softwares of mine have claims that only one person may use it on one machine at one time. What does this mean? If two Excels are loaded on the same machine at the same time where is the licensing happening? No check over network will find any but it's own self running when really it's running for another user anyway on the same machine and that would still end up being a violation of the licensing of a product.
This seems pretty simple to me, if the license says it can only be in use on one computer at a time, then both of you can use it. It's not like multiuser computers and compatibility execution environments didn't exist when the vast majority of licenses were written. If it says only one copy of it can be in use at a time, well the copy in memory which is executed is definitely a copy, from a technical standpoint, so both of you cannot use it. Finally, if it says that only one instance can be running at a tim
Anandtech didn't seem to care about potential licensing problems (at least they didn't mention it):

We also saw no perceptible difference in performance when we ran the 860Twin as a single user or with 2 users working. We can only assume that the time-slicing mechanism used to enable Magic Twin w
The difference here is that you pay for a license to use it on your computer. It's just multiple instances on the same computer - there's no network in use here, and the 2 end users are sitting AT the same computer, which just happens to have more than one monitor. Licenses distinguish about running over a network by saying that the application is being displayed and interacted with on one computer, but is hosted on/executed on another, interonnected by some kind of network.

I remember reading that the original arguments in favor of software licenses was this:
Computer code is protected under copyright, every time you run a program, it is being copied from your hard drive (or other storage medium) into the computer memory. So, you are not allowed to do this (you are not the copyright holder) by default, and by agreeing to the license you are allowed to make the copy (just like the GPL, conceptually).

Thats a great idea. Never seen anything like it. I have similar problems. For example, while my sister visits barbie, I wouldn't get kicked off,we could both be on it and not know it. Playing two intensive games at once might not work though. Its a great idea. All I can say
Is it me, or is this returning to the days of dumb terminals? I think this is practical for some of the suggestions they had, ie. 2 children doing homework, but this is hardly a revolutionary idea.
This site is owned by a Linux company. Didn't you know that?
It's kind of an amusing joke--all the anti-capitalism spiel you read daily here, all done on a corporate-owned website...OSDN's "tech news" site which just so happens to post a lot of articles that are derogatory toward competitors.
Well, minus multiplied with minus becomes a positive. So I guess it would cancel out. On the other hand, Windows would probably BSOD when trying to multiply something. So, we get (--)-, which is -. A BSOD. Now, if the bluescreen subroutine (known internally in microsoft as "void releaseDateFixer(void)") also BSODs, you would be back in the graphical interface again. To crash the BSOD routine, you would probably need to do something as cruel as... plugging in a new printer or something.
These are nothing new. The PCBuddy has been around for a number of years. We don't pay much attention to this stuff in the USA because PC's and parts are cheap. These devices are popular in third world countries where resources are streched.
My Mum (a teacher) used to use something like this in her school, to save money. It was all software based IIRC (except the switch so you could have a monitor, keyboard and mouse each). That was at least 5 years ago.
Two users on my PC at once?

It kept saying low cost, but no prices (or resellers) were mentioned, and the manufacturer decided that everyone had to have shockwave to view their website:-(
the PC model is kind of really not that good of an idea, all things concidered. I am sure those of who are network admins or some such at companies know that individual PCs on the desks of the employees is headache central. Why not take the terminal server model into the homes? There would need to be only one machine, it could sit in the closet w/ the cable modem or whatever, out of the way. Perhaps with a CD changer or virtual disk mirrors to keep it from really needing to be accessed. Then there could be wireless heads around the house, one for each member of the family, say. Then everyone can use the computer at the same time and need only one copy of the OS, anti-virus, et cetera. It'd be a lot neater to handle.

AKA, the "Network Computer", or "NC". Two problems with that model: Vendors wanted direct control for licensing and software distribution considerations. There still aren't enough high-bandwidth Internet connections for that to become popular. Plus the schemes proposed were pay-per-use, which consumers apparently hate.
Does the hard drive look seperate for each user? Or are they piggy-backing onto the Fast User Switching / Built-in Terminal Server feature of XP to provide user seperation?

Buddy betwin - Betwin B-680 - Enables 2 Users or more to share 1 PC
Sometimes one computer just isn't enough. With buddy betwin, you don't have to spend thousands of dollars on a second PC. This device lets you connect a second keyboard, mouse and monitor to your existing computer to create a second, fully functional PC. Share drives, printers, scanners, software, and even surf the Internet at the same time using only one modem, one telephone line and one Internet Service Provider account. St
Maybe the first SFF, but I remember seeing a PCI card available in some catalog somewhere that would allow you to do this with any PC. Anyone remember the name of that one?
It's not unique. This has been around for more than a decade. I remember an add on card for sale in CompUSA that allowed this exact thing.
I never bought one, because I never had a need. But this is no unique, in so far as allowing to people to use the same box via a mouse and keyboard. It's kinda nice to see this functionality updated, but it's certianly not unique.
However, it leads to some legal question for software licenses.
Most EULA's say you can run "One instance of the software on ONE machine at a time" - how does this apply to this machine? If you run two instances of a software package on the same machine, are you in violation of the EULA? My gut reation is yes... but will they really care?
Depends. If it's not popular, this obviously won't be inforced, but if this is something that becomes more popular, will we start to see software that won't let you run multiple instances of it at once?
The article says you can play head to head VGA games against each other... but how does that work if you're only running one instance, or are you running two instances?
This just doesn't seem all that practical for game playing. For productivity apps, though, this could be killer for cube rats. IT could deploy one machine for two cubes, cutting your hardware budget, and support in half!
Lots of questions, both technical and legal need to be worked out before this could really take off. Couple that with the fact that previous attempts at this didn't seem to fly, for whatever reason, it makes me wonder if this isn't already a dead technology.
I think you need to define "one instance", and you need to find out whether "run" is included, as in "run one instance..."
The reason that's important is you could INSTALL one instance and RUN multiple instances on one machine at a time. Most applications (MS Word, Excel, etc.) allows multiple instances to RUN on one machine, but not necessarily allow multiple instances to be INSTALLED on one machine.
In those cases, in any case, we know the intention is really, one user per license per machine. In many a
You're right this isn't unique, in fact they had a mini-computer called the Virtual PC Buddy B-210 [active-hardware.com], but the main difference between the Jetway machine and the PC Buddy, is that the PC Buddy could share it's resources with up to five people, instead of Jetway's two.
For productivity apps, though, this could be killer for cube rats. IT could deploy one machine for two cubes, cutting your hardware budget, and support in half!
Hardware budget in half? Not if you still need two screens and two sets of input devices. And the computer itself will be more expensive than a normal one, so the gain would be less than the cost of a single machine.
As for support... well, software support is what costs money, or so I believe. It comes down to whether it's proportional to the num
Well, given the price of a good bookshelf system nowadays I would say that from a space-efficiency standpoint you're just as well off with two separate machines. And so far as IT goes, when you need to upgrade a system you now have two workers idle instead of only one, and if the hard drive blows chunks you also have two workers idle instead of only one. My feeling is that this would be great if computers cost $3,000 instead of $300: it's a solution to a problem that disappeared long ago. It's dead tech,
Yeah, it was called the Buddy, and the old incarnation sucked. It was a PCI board which was essentially a video card plus a PS/2 keyboard and mouse controller. The video capabilities were terrible (sync rate limited to 60Hz, IIRC), and the second keyboard was prone to random resets and other problems.
The new incarnation of Buddy [ipc.com.sg] seems to address all those problems by using standard hardware. Buddy and BeTwin (they look like the same software) appear to work with any PCI video board that'll coexist with other video hardware, and since they use USB keyboards and mice (and audio, if you want), the proprietary controller problems should be gone too.
The new Buddy doesn't stop at 2 stations, either. It'll happily run up to 5, which might have a chance of using some of the absurd CPU power available in a modern PC. They have a trial version up for download, I might have to check my hardware compatibility and tinker with it later.
If you've got a multi-monitor set up, at least with 2 separate gfx cards (one AGP, one PCI), each one can have it's own D3DDevice object.
You can run them both at once:)
But 99% of games just use the primary device, and don't give you a chance to use any others...
It appears that it doesn't even do the dual user function out of the box From the article "What Do You Need for a Twin PC?.... Dual Head VGA - the 860Twin comes with just a single VGA connector, so you must add a Dual Head VGA card for Twin PC operation."
So I would buy this box, then have to immediatly buy a new graphics card, thus making the one it came with useless?
Hard to see the advantages of this thing outweighing two seperate machines.
not a single thing was said about how it works. How does the 2nd keyboard direct its keystrokes to the 2nd display ? Is the 2nd display an RDP client, or is it a 2nd monitor of window session 0 ? Are the two users running as different XP logins ? what does the magic twin software do ? new keyboard driver ? new mouse driver ? new audio driver ?
Without knowing how this thing works, it's a non article.

What will this do to Grandma and Grandpa computer user? Imagine your grandparents out getting their first PC.
this is one of the most useless ideas out there. I don't see any reason for people to purchase hw so they can use the same Windows box. PCs are sufficiently cheap right now that you're better off buying two and hooking them up over ethernet. You can still share files, share apps, etc. but crashes will affect only one user rather than two. Windows is not a multi-user system... it was designed for one user, and when it comes down to it XP is just a hack for multiple profiles.
A real solution, that's already been mentioned here, is having one Linux box and setting up multiple desktops with VNC. That's if you absolutely must combine your systems or want to have apps installed on one setup. You can have as many dumb terminals as you want hooked into that machine.
Making a machine multi-user is a software problem not a hardware one and this idea will FAIL.
We can only guarantee that the program will properly run on a completely reinstalled Windows XP system, using the latest hardware drivers and system requirements,
without third-party software and hardware.
.. so as long as you don't try to run any applications on it, you'll be fine! The software is fully tied to Windows XP, so no chance of running other operating systems. It looks like there is only one copy of Windows XP running, but then Page 13 has this quote:

If your choice is "NO" then at every restart the software will notify you of this issue.
Page 8 tells you to turn off the system standby in XP's power management. Guess they don't have that working well. But they do warn the second user if the first user decides to shut down the system.

Im really curious to see how they handle head to head gaming... Although they didnt mention it in the article, i can imagine that some sort of clever networking setup was required, for both "machines" to be recognized by any modern game. My best guess is that the primary "slice" runs as a NAT server for the secondary, but this is simply speculation. Anyone have more info on this?

Many, many years ago, I came across an article in a Hong Kong magazine regarding a piece of software called "Betwin," which does the same thing. Googling will find you links like: Buddy [getabuddy.com] and Another version called Buddy Betwin [newworldtelnet.com]
Basically the same thing... Nothing new here, move on...
I have a laptop which obviously has it's own keyboard, trackpad and LCD - that's the first user. I also have a second monitor plugged in, and a USB keyboard and mouse. It seems to me that if the software could cope with it, a second person should be able to use the computer at the same time.
Unfortunately I haven't got the second monitor working under Linux, (crappy drivers from VIA) otherwise it would be simple to run another X server linked to the external devices. Windows runs the second monitor OK, but it doesn't have any way to run it independantly of the main user.
I have ended up using an old SGI Indigo to run programs on the laptop over X for the second user, which doesn't always work with modern X programs.
I already did the same thing with plain old X-windows on a linux *LAPTOP*. Windows is so behind the times. (With X, you can define the two outputs of the video card (VGA out and the LCD screen) to be different screens altogether, and define one to use the laptop's keyboard and laptop's touchpad, and the other to use a usb keyboard and mouse, and violla, localhost:1.0 is user 1 on the laptop, and localhost:2.0 is user 2 using the usb keyboard, mouse, and the external VGA monitor.)
Not a whole lot keeps two X servers from running locally. I saw this howto at tldp.org a few months ago, and was very interested. It requires a kernel patch or two, but it seems very nice. http://tldp.org/HOWTO/XFree-Local-multi-user-HOWTO/ [tldp.org]
This is restricted to only two users, isn't portable across a network to other machines, requires rather specialized hardware, and will cost you money.
It's a lot harder to get a dual consoled Linux desktop than a dual X-windows Linux Box.
If you want multiple consoles with seperate keyboards/mice, then you are looking for The Linux Console Project [sourceforge.net], I've never played with this
If you just want multiple X-Sessions running with sperate keyboards/mice, then you should just need to seperate all your keyboard, mice, and screens into sperate ServerLayout sections of your XF86Config-4 file. check here for documentation [faqs.org], This isn't actually all that hard.

This same licensing system is also required by many/most other commercial vendors. Anyone familiar with Terminal services or Citrix should be familiar with this licensing model. If they aren't Microsoft will enjoy speaking with them.

For a better question, I wonder if anyone (other than Microsoft) will care.
Not a troll or flamebait - Really, how many home users actually went out and bought Windows or Office? For a business, a few hundred bucks might not mean much (particularly in comparison with getting caught running an unlicensed app). For a home user, many people balk at even paying $50 for their tax software, nevermind something as mundane as a word processor and spreadsheet (and the rest, that I have yet to see anyone use outside a work environment).
People get Windows with their machines. They get Office from a friend or borrow the install CD from work. Legality simply doesn't matter, end of story.
Or, for an already-common analogy, how many people paid extra fees to use on a dual-CPU box (most commercial software includes provisions limiting its use to on a per-CPU basis as well)? Answer? No one. Even businesses usually overlook that one, for "mere" duals.

I know many softwares of mine have claims that only one person may use it on one machine at one time. What does this mean? If two Excels are loaded on the same machine at the same time where is the licensing happening? No check over network will find any but it's own self running when really it's running for another user anyway on the same machine and that would still end up being a violation of the licensing of a product.

I never bought one, because I never had a need. But this is no unique, in so far as allowing to people to use the same box via a mouse and keyboard. It's kinda nice to see this functionality updated, but it's certianly not unique.
However, it leads to some legal question for software licenses.
Most EULA's say you can run "One instance of the software on ONE machine at a time" - how does this apply to this machine? If you run two instances of a software package on the same machine, are you in violation of the EULA? My gut reation is yes... but will they really care?
Depends. If it's not popular, this obviously won't be inforced, but if this is something that becomes more popular, will we start to see software that won't let you run multiple instances of it at once?
The article says you can play head to head VGA games against each other... but how does that work if you're only running one instance, or are you running two instances?
This just doesn't seem all that practical for game playing. For productivity apps, though, this could be killer for cube rats. IT could deploy one machine for two cubes, cutting your hardware budget, and support in half!
Lots of questions, both technical and legal need to be worked out before this could really take off. Couple that with the fact that previous attempts at this didn't seem to fly, for whatever reason, it makes me wonder if this isn't already a dead technology.

The new Buddy doesn't stop at 2 stations, either. It'll happily run up to 5, which might have a chance of using some of the absurd CPU power available in a modern PC. They have a trial version up for download, I might have to check my hardware compatibility and tinker with it later.
