@anti-bearshare. I think what he meant was the possibility to reconnect to the network comfortably without making use of host-caches.

@Unregistered(2). You could send a public-key with any of your Querys, so the QueryHits could be encrypted for you to decrypt again. - The problem could be I) each Query would grow by 64 to 128Bytes (512-1024Bit or would you consider a weaker encryption?). II) I don't know how that would affect for example ultrapeers sharing lot's of files and having a good connection to the net, because they would have to encrypt many QueryHits. I'm not too familiar with the performance of encryption mechanism but I can imagine it will spoil some peoples fun if gnutella clients use 90% of their system resources.
