Again, that sounds more like your gaming group, though the fluff does lend itself to that in some ways. But when you think about it, thats how stuff will end up. Of course the net will be populated by that stuff. Did you think it was going to go away in seventy years?
But the scanning thing is really a gaming group thing. I tend to play with a bunch of guys who still like the pink mohawk style, but when I gm I keep them on their toes. Not by scanning them all the time and crap, but by taking note of when they forget about a datatrail, or if they leave bits of clothing and stuff at the scene. Sometimes they catch it, sometimes they dont. Makes for great plothooks.
