It sounds like you need your own "ServerMediaSubsession" subclass, 
similar to (but different from) "PassiveServerMediaSubsession".

In particular, you will need to write your own implementation of the 
"getStreamParameters()" virtual function.  Each call to this function 
can result in a different multicast address being used (if that's 
what you want).  You can also use the "clientSessionId" parameter to 
distinguish between clients, so that your other virtual functions can 
know which client was given which multicast address.
