I was going to post in the preview of the new iTalk post but I didn't want this getting lost there...
This is a document describing the implementation of the TOC protocol (Talk to Oscar Protocol, the only official protocol that AOL allows to be used to communicate with AIM)
I "should" be easy to implement without any core modification to iTalk, also for some examples and some more in deep explanation of the protocol, go here
Hope that helps.
