Tor is a big problem. It gives you anonymity, but, it still requires someone to forward your traffic, or multiple forward hops. You really need a proxy dedicated server like what The Pirate Bay has (you pay for it) which does not keep logs. Otherwise everything is incredibly slow. And I mean 56k speeds slow or worse.
Sorry, I was considering whether running a your own Tor proxy gives you some degree of immunity from prosecution rather than suggesting sending your own torrent traffic out through some other poor souls network connection.
