It was really good, but I'm sure the gold was entirly unnecessary (I could detect no difference in the taste in the bites with the gold leaf). I should have tested the resistance of my skin with my multimeter both before and a while after eating the cake. What would really be funny is if it did in fact make a difference.

A credit card reader could read your body's electrical signal, as it is also scanning the card. Added consumer security. Even cooler would be if each person had a unique electrical signal their body generates, but I don't know anything about that. Either way, interesting.
You could make long distance calls from anywhere, and have the phone read your calling card number automatically when you pick up the phone.
Possibility of electronic "keys" for car/house stored in PDA. Not so good if PDA is lost or crashes, but if you can call the company and say "My PDA is gone - please scramble my house key codes until we can resolve the issue" it might work. Locking the house would be great - simply disable the electronic circuit from the inside and there is no lock to pick. As for someone who tries to crack it while you're out, simply have the system stop taking input for five seconds if it gets a bad signal. With billions of possibilities at five seconds a try, it wouldn't work real well trying to crack it. If you're paranoid, have it take thirty seconds. No more fumbling with keys or those little remote control keychains, either - just touch and open.
Many issues to resolve, but some very cool possibilities as well.

Absolutely.
Although, I am telling you right now, if we greased our palms with conducting paste, and gripped REALLY hard, we could get down to 100 kOhms in conductance. Then we deal with noise. Now, most of the connecting tissue is stricly low-pass (which is a bitch for high bandwidth issues), and noise is in the millivolts range. To add insult to injury, most of the signal loss will occur in the skin itself, so this application is a really tough one. I think in the lab you could probably rig it to transmit the amount of info in a business card, maybe.
OTOH, detecting a handshake and using that to trigger an IR linkup seems fairly easy.

Some Clarifications (Score:5, Informative)
First, 10 Mbps is possible, but that's getting near the theoretical limit. The datarate is limited by the bandwidth, and the bandwidth is limited by the fact that around 50MHz, the signal wavelength is about four times the size of a person, which means the person turns into an antenna, and the whole system becomes essentially a short range radio.
Second, because these systems operate in the near field, the signal travels through a current loop, and not as plane waves in free space. This means that there has to be some kind of grounding path for current to flow back to the transmitter after going through the person. This is why it works so well to put transceivers in shoes -- the ground path can flow through earth ground (or any conductive material in the floor). For devices held in hands, the very small (femtofarad) capacitance of free space is enough, but the signal does suffer more from noise. Devices in purses, etc. also have this problem, and may have difficulty establishing the ground connection depending on the material the purse is made from and the other objects inside it.
One issue that to my knowledge has not been addressed very well is guaranteeing that the signal is received during--and only during--physical contact. There is a large dependence of signal strength on geometry. The devices I've constructed can communicate when they're brought near (~10 cm) of each other, touching or not. There are a few solutions, such as looking at jumps in signal strength, but they tend to be confused when a person without a transceiver happens to touch the object, and a person with a transceiver is nearby. I'm currently working on this problem for my PhD dissertation, so if you have any good ideas or know of related work, I'd love to hear from you.
If you'd like to read more, the first (and most detailed) publication I know about on this idea was Thomas Zimmerman's Masters Thesis at the MIT AI Lab. You find it here: http://www.media.mit.edu/physics/publications/thes es/95.09.zimmerman.pdf [mit.edu]

"Wog", a disparaging British slang term for non-European "native" peoples, or in some constructs ("the wogs start at Calais") anyone not British, probably derives from Golliwog, a rag doll with African features in a children's storybook, though some probably apocryphal folk etymologies claim it's an abbreviation -- sarcasticly-applied -- of "Worthy Oriental Gentleman". Apparently the term is also applied, derisively, by mmebers of the Church of Scientology to non-Scientologists (?).
In any case, all these terms are considered disparaging and offensive, especially when used by persons of whom they are not descriptive. (Although "nigger" finds a use, within the black American population when applied to others of the same ethnicity, similar in meaning to "(that black) person".)
