That's fully expected, I plan to tackle adding support for this in both Pidgin and Adium.

Is there any built-in assumption that user accounts will be in email address form?  IM handles are not always in that form for services that are not XMPP/Jabber.  Can you point me towards where to start for including OTR keys in my PGP key?
