This list is fine for that.

The "use GPG keys for OTR" suggestion comes up pretty regularly.  But
most GPG keys don't have your IM username and network in a canonical
format in them, so you'd have to manually associate the GPG key to the
IM buddy anyway.  Is that better than manually associating the OTR key?
Is it better than using the Authenticate Buddy mechanism?  Note that
keyservers don't help you much if at all here.

Or are you suggesting one of the timing-based MITM detection protocols?
