    This interface should be *IMPLEMENTED* when writing a "receiver" transport plugin,
    which can be linked to TRtcMessageClient in place of the TRtcMessageServer component. }
  IRTCMessageReceiver = interface
    ['{C9E3606F-ED08-43F4-AF97-F55A3EC8F14B}']
    { ProcessMessage need to be called *only* once per request, with a complete request data 
      waiting in the "aRequest" stream and an empty "aReply" stream to receive the response.
      Request processing is done in a "blocking mode", which means that the caller will
      have the complete response filled in the "aReply" stream, before the call returns. }
    procedure ProcessMessage(aRequest, aReply: TStream);
