Receiving AirPlay RTSP

I am interested in writing an application that can receive and play
audio from an AirPlay source. I have the mDNS/DNS-SD portion working so
that iTunes sees my application as a speaker. However, I am unsure of
the best way to receive the audio.

Right now, iTunes tries to begin by sending the following (as captured
by nc):

	POST /fp-setup RTSP/1.0     [ I'm not entirely sure what is going on here yet.]
	CSeq: 1
	Content-Type: application/octet-stream
	Content-Length: 16
	User-Agent: iTunes/10.2.2 (Macintosh; Intel Mac OS X 10.6.7) AppleWebKit/533.21.1
	Client-Instance: 69EFB31E9A3589A3
	DACP-ID: 69EFB31E9A3589A3
	Active-Remote: 687528207


I have looked at GStreamer's rtspsrc, but it needs to connect to an
existing server. What I think I am looking for is something that will
listen on a port, similar to tcpserversrc.

Is anyone working on a similar project?
