Yeah, relaying is probably the last big thing I need to add before
releasing Spook 1.0.  (OK, the last big thing that I haven't implemented 
yet in my private tree, anyway.)  This is actually somewhat complicated 
because it requires an RTSP client implementation to set up the 
Spook-to-Spook media session and an RTP client implementation to receive 
the media from the sender.

I can probably shortcut this a bit by implementing only the RTSP client 
part and using Darwin Streaming Server as the relay server.  Does anybody 
have any opinions for or against DSS?  Would relaying through DSS be 
usable and useful, or is DSS more trouble than it's worth?  -Nathan
