They've released a little program called "Peerguardian" and it blocks IP addresses from the RIAA etc...It's incredibly useful if you're paranoid since you have so many mp3's but I suggest you go through the forums and download the old version (1.97 I think) because the latest version has a lot of bugs that are yet to be fixed....although they are working very hard at it..
Lots of run-time errors, etc..
All of us will probably need some kind of program like this soon...all we can do now is stay alert I suppose..
Take care,
