No.  The idea of multicasting a message to a group is that every member 
should receive it.  However, since the clients can know the membership 
of their groups from regular membership messages, they could conceivably 
choose to only send the message to the private group of one member (this 
should be easy to implement by wrapping SP_multicast).

The notion of "first available" in this case also seems to be 
problematic.  Choosing a first member to send to at random, and then 
rotating in the order of the membership list should be fine for one 
sender, if the load balancing goal was just to send the same number of 
messages to each group member.  However, "first available" suggests some 
sort of global knowledge about clients who are ready for another 
message, which would require messages to be sent, or some other form of
