I hate to be a party pooper on the "we cant get bum k'd by the RIAA" but we can

they can still do mean things to you and i from the states, they just pass your details over to scotland yard, who then can choose to prosectute you for copywrite infringments, thats part of my job, to track people who "hack" and deface websites, for the police... odd how most of my workmates download gigs of illegal stuff a day

not i ofcourse ;-)
anyway, the IP blocking systems dont work, the RIAA work on a huge range or dynamic IPs, using provided access from companies you wouldnt expect to see, most artist recording sites have granted access too, so you could see snoop.metalica.com in your list if they get that bored.
