Six Degrees and Paranoid P2P (Score 1)

People will stop sharing cuz their scared, what we need is secure P2P. Waste's encrypted mini-network is cool, and possibly safe, but trading with people you don't know is the whole point of P2P. What if you could have a list of trusted friends who were the only ones that could connect to you directly? A trusts B and they share files. B trusts C and they share. A does not trust C, but C ask B about a file. B knows that A has it, but does not reveal the identity of A. Instead A send the file to B and B forwards it to C. Not the most efficient, but safe. I know these ideas are not all knew (freenet) but I have not seen anything like this that is easy to use.
