The first comment by Mailpile seems to highlight the biggest problem to me:
>Hello! Bjarni from the Mailpile team here.
>This is an interesting proposal and sounds like a significant improvement over the current centralized key-server model.
>The main quibble I have with it, is it seems there's no concern given to the privacy of user's communications - the proposed gossip mechanism seems designed to indiscriminately tell everyone who I am communicating with. That's a pretty severe privacy breach if you ask me, worse even then PGP's web-of-trust because it's real-time, current metadata about who is interacting with whom.
