A cool idea

[Nate]

It wouldnt have to be a virus.  Make a normal program that people can download.  Each person gets a unique signature.  Wireless device sends out that signature and the others it has accumilated to others.  Easy enough to track distribution and spread.

No.  Then people would have to make the choice to get it or not.  You don't get a choice when you're infected with a virus.  Besides, that would target a much more specific niche of people that use technology.

iago's idea would produce much more accurate results.

I think something neat would be if somebody found an exploit in Windows' wireless stack.  Write a worm for it that spreads by walking near somebody who is infected.  Release it quietly, and track the geographical progress.  It would be just like a people virus. :)

Something sorta like this has been discovered.
