You realize, I hope, that both "RTSPClient and "RTSPServer" *already* 
supports unicast streaming.

There is no RTSP "SEEK" operation.  Presumably, you mean the RTSP "PLAY" 
operation, but specifying a non-zero offset in a "Range:" header.

This would not be done in "RTPSource" (because that's used by *clients* 
only).  Instead, (optional) support for seeking would need to be added to 
the "FramedSource" class, which the RTSP server uses to supply outgoing data.

I haven't thought much yet about how much work would be involved to do 
this.  (This is not yet a funded task.)

Again, "RTPSource" would not be the class to change.
