Yes, and its parent class: "MultiFramedRTPSink".

Yes, but RTP packets can also be sent over TCP, using the same TCP 
connection that's used for RTSP.  The "DarwinInjector" implementation 
currently does this, because I figured that it would usually be considered 
important to transport data to the DSS reliably (and also to make it easier 
to inject the stream to a DSS that's on the other side of a firewall).
