Well, well , well. Look familiar ? Bittorrent's bleep. It died , I think because the feds took over the bittorrent company and then killed off this idea. Probably too much if a threat ? There may be open source forks out there ?

"With BitTorrent Chat, there aren't any "usernames" per se. You don't login in the classic sense. Instead, your identity is a cryptographic key pair. To everyone on the BitTorrent Chat network at large, you ARE your public key. This means that, if you want, you can use Chat without telling anyone who you are. Two users only need to exchange each other's public keys to be able to chat. "
