What seems strange to me is why copyright owners (and the governments they bribe) are going after individual file sharers in the first place. It would be much easier (and more effective) to strong arm ISPs into blocking access to HTML based p2p indexes like the Pirate Bay. Kinda like the great firewall of china. I know that's the start of a slippery slope to free speech violations, but then what they're currently doing is an equally slippery slope to privacy violations (and really privacy is an essential ingredient of free speech).
All that's really needed to kill file sharing is to make it sufficiently inconvenient, and that's (relatively) easy to do for the vast majority of the computer illiterate public.
Fortunately, it appears that the copyright lobby is rather incompetent
