I have a proposal for making Gnutella a little bit more anonymous

a) All clients should hide any data that would give information about other IPs. Like ListView fields or HostCache data or temporary data files for downloads. All IPs should be encrypted. Like Xolox does for its HostCache data.

b) Instead of an IP, a nick name should be used to identify other clients. It is not nessecary to be unique for all the Network, just some info about the host you are connected. It could also be used in chats between two clients
