That is Very Complicated, because it's not obvious what "deniable" and
"off-the-record" mean when there are more than two people involved. We
have a tech report that addresses that question:
Multi-party Off-the-Record Messaging
Ian Goldberg, Berkant Ustaoğlu, Matthew Van Gundy, Hao Chen, CACR Tech
Report 2009-27, June 2009.
But for now, the answer is that OTR can only be used between two people.
So you can set up all-pairs OTR communication, but Bob has no assurance
that Alice sent the same messages to him as she did to Carol.
