Wow, good point.  There was no mention of that in the Protocol document.
But I've added this paragraph to the Key Exchange Message section:

Sorry for the oversight.  In gaim-otr, you can see the fingerprints
(both yours and other people's) in the UI panel, as well as the popup
that happens when a secure connection is established.
