The only realistic compromize I can think of would be to have a one- way invite combined with offline verification: You feed the invite to your node, then it

Or, reminiscent of zphone, there could be a 'verification code' which is a hash of the link encryption keys (one listed for every peer); which would show up as the same on both ends if there is no MITM. This short code could then be verified out-of-band, or *perhaps* cleverly in-band (as zphone does; can a MITM simulate your voice?/videochat).
