Putting higher priority on a host or any group of hosts is still centralization, doesnt matter how you word it. The hostcaching thing, works fine for me. I dont really understand the purpose you're trying to explain.
Authentification works with encryption, hence public and private keys (since you've mentioned PGP, I'll assume you know what those are).

heh, I dont really understand what you're saying here, well b/c PGP (Pretty Good Privacy) does ENCRYPT files/messages/etc!!!! So that statement didnt make any sense.
decentralized forum thing would be a cool project.
