/*

  This class allows for jrtp to process packets without sending them out 
  anywhere.
  The incoming messages are handed in to jrtp through the TransmissionParams 
  and can be retreived from jrtp through the normal polling mecanisms.
  The outgoing RTP/RTCP packets are given to jrtp through the normal
  session->SendPacket() and those packets are handed back out to the
  client through a callback function (packet_ready_cb).
  
  example usage : Allows for integration of RTP into gstreamer.

  THIS HAS NOT BEEN TESTED WITH THREADS SO DON'T TRY
