This opens a new category of attack, one that I wasn't all that
concerned about.  Namely, the guy on the other end isn't trustworthy.

To a large extent, peer authentication allows users to make their own
assessments, but we have to acknowledge (and likely accept) that the
other guy isn't necessarily trustworthy.  I think that we can rule the
age-old human problem out of scope, but perhaps we should be clear
that we are doing so.
