I've currently been using ZeroTier One in order to authenticate peers and avoid MITM situations. Seems to work well so far with only about 30ms added to the ping time compared with to direct IPv4 connection.

Thinking about this, I don't think a simple AUTH set of messages will prevent MITM unless every message uses some form of PKI. It's not enough to just have a few messages exchanged to establish identity.

@rebroad: I'm interested to read your concerns on the mailinglist. Be aware of the conjunction with BIP151. A "simple set" of AUTH commands together with a preshared key (and on top of BIP151) can protect against MITM attacks.
