Curious Blend of VPN, PDA and USB Drive 84

Posted by michael from the if-you-build-it-they-will-come dept.
An anonymous reader writes "Realm Systems has developed a cellphone-sized mobile device that takes advantage of the hardware of a another PC by attaching via USB. It requires an Internet connection to connect to a backend system, but acts as a fully functional PC with dual PowerPC processors, a 20 GB drive and all your applications - if you can find someone who lets you connect to their PC. An interesting option especially for a price of $195 for the mobile device." So, for a $10,000 central server, a $1000 PC, and a $195 device, you can have the computing power of: a $1000 PC. It seems like there might be cheaper ways.

      It's not for you, it's for large companies. Now that I understand what it is, I think it could actually be useful. The article didn't help much, but if you want to know what it really is:

      It is a USB hard drive + integrated computer running something like knoppix + fingerprint scanner, in a package not much larger than an iPod. You take it with you anywhere, then plug it into any computer you find. After scanning your fingerprint it automatically takes over that computer and brings up your suspended Linux desktop on the screen, just how you left it. It also sets up a VPN over the Internet to access your company's intranet so you can work just like you were in the office. When you're done you unplug it, which instantly suspends your session until you plug it in again.

      The central server is cool because it backs up all of the devices as they are being used, so if somebody loses theirs it's not a problem. You can just copy their backed-up image onto a new device and give it to them. You can also track usage and do security junk like that. I'm not a big fan of that feature, since it will probably lead to stupidly restrictive policies that are automatically enforced with an iron hand by the software. But that's a management problem, not a problem with the technology per se.

        My guess would be that it puts it into hibernation and then boots from USB.
        • I've never seen a PC capable of doing this. The BIOS knows it's been hibernated and resumes immediately. So, without knowing how to clear the BIOS's flag (good luck getting this from BIOS vendors), this is not likely. Additionally, some machines cannot boot from USB. And "any computer" includes things that aren't x86 PC's.

          However, it's a good theory.
          • The BIOS knows it's been hibernated and resumes immediately

            Not on mine. On mine (when I had windows) if I put it into hibernation, it just saved all its memory onto disk, and then at next boot it just reloaded it.

    I think that this is probably targeted at roaming corporate users. I split my time up between three corporate offices, a day here, a day there. Since I only have a cubicle in one of the three, I'm always having to use someone else's computer who's out for the day (it's a big company, there's always someone out). Each of the other guys in my group are in the same scenario.

    Our roaming profiles give us access to our documents when signed on to someone else's computer, but they don't give us access to our developer tools. We've thought about external USB / Firewire drives, but not all of the tools we use can work running right off a detachible device.

    This sounds like it might offer a better solution.
    • Why don't your roaming profiles give you access to your development tools?
      • Because a roaming profile only set's up your profile, it won't install apps that aren't already on the pc. Profile = shortcuts, drive mappings, application configs, etc.

          • drive mappings...

          And you're not a system administrator either, are you? The applications don't have to be installed on the local PC; they need only be accessible from the PC. Now, there are some bad applications that need registry entries and/or local configuration(s) on the host machine (eg. Exceed), but that's workable from a logon script. I've been places where I could logon any machine in the network and go to work -- both with Windows (TM) PC's and UNIX (tm) systems. (It's easier with UNIX (tm),

      • It's using the host PC as a thin client, and running the storage and CPU on the portable box, using the USB instead of an Ethernet.

        I haven't figured out what actual functions the central server provides - probably a VPN tunnel server and some authentication, and maybe also file serving for people who need more than the remote device provides, but to me it looks basically like a license server to extract cash from the customer in return for cheap remote boxes.
