It's not clear exactly what you're proposing.
I think Ricochet / Invisible.im is aiming for peer-to-peer
(serverless) chat between pseudonymous users.
If you give up peer-to-peer you could have both parties connect to a
chat server via Tor. But then the server can tell which pseudonyms
are talking (unless, I suppose, you start doing tricky things with
shared secrets like Pond/Petmail delivery tokens).
If you give up pseudonymity you could have both parties make a direct
But if you want pseudonymity and peer-to-peer, it seems like you need
*some* sort of pseudonymizing layer like Hidden Services or Nym
Servers or Pond mailboxes or something?
