Hm, I guess I could read up on this, but how is somethig like a group chat 
constructed if none of the participants have no knowledge of who is who in a

(I think OTR folks is struggling incredibly hard with getting this to work

Yes, the ideas may perhaps be well suited for, say, private messaging parts of 
a protocol. When not even the servers should know contents of messages or 
relations between contacts.
