Hide IP on p2p?s

For legal reasons and use you can use a lot of softwares that can help you to hide your IP address, me I hide my IP (not for p2p!) using goliberty : http://www.themobiweb.com/en/Go-Liberty/Go-Liberty.html

You can try this
http://www.privacyconnector.com
It uses VPN solution.
It encrypts all your outgoing traffic and make you surf Internet anonymously. But their speed is not fast...
But I don't know it will work on P2P software or not

and oce again, if you want download soft anonymously you need vpn client with encryption and no logs (because provider may give them to someone who is intersted in it - police, for example)
to have no problems use http://eztun.com - really grear service, with goog prices. also you can use someting from that list http://www.experts-exchange.com/Software/Security/
