Encryption is NOT dangerous. Fasttrack is sued because it's not working completley decentral, not because it's using a kind of encrypted key exchange for a proprietary authorization mechanizm.


Encryption makes no sense in a peer to peer system, at least as long as download partners are not anonymous.... or as long as content is not anonymous! Look at Freenet, a user has no idea what is on his/her harddisk.
Similar to anonymous Freenet, but much much simpler, is swarming technology. Thousands have a small part of a file without knowing it.... so content is made (slightly) anonymous. Isn't it?

More ideas for Gnutella's future?
