Quite true. Hey, there's your working DRM - inability of downloaders to learn regular expressions!

Mmm.. no. The chief drivers behind people's torrent skillz have been music, pornography, software and movies. How likely is that the first contact with filesharing for anyone was something related to books? As to filesharing moving to higher age echelons, my napkin math tells me we are currently seeing slightly less than half of max growth potential. Assuming that eventually it will spread to everyone between ages 15 and 80. So that would make max potential harm from filesharing to about twice as bad as it is now.
Wait.. Porn! Pornsites are commercial, right? Do -they- use DRM?
