There's someone who will be working on OTR this term, and fragmentation
support should be one of his first tasks.  So watch for a fix.  :-)

That's one of the stated future directions of OTR.  Probably not this
term, though.  One of the tricky bits is determining exactly what
you mean by "deniable authentication" in a group context.  During the
conversation, should Bob be able to tell that this message came from
Alice, and not from Charlie, or just that someone in the chatroom sent
it?  After the conversation, of course, we'd like complete deniability
and forgeability.
