No.  RTCP is assumed to use the next (i.e., odd-numbered) port.  It is not 
explicitly mentioned in the SDP.

No, RTCP will always be implemented by default, because the standards 
prescribe that RTCP should be implemented.  If you really want to, you can 
remove the calls to "RTCPInstance::createNew()".  You shouldn't need to 
though; RTCP doesn't do any harm (and does a lot of good), so you should 
just keep it.
