I have a patched but not-distributed version of mplayer which
does exactly what you want.

But, it fails to:

   (a) keep a/v sync,
   (b) display video without artifacts,
   (c) keep playing audio (broken frame errors)
   (d) not crash due to full buffers.

So, I'm not sure that you would want it!

It should be very possible to make vlc handle what you want
to do, although the facility is not there at present.

The raw udp multicast client aspects of vlc work really well
and there is RTSP support for unicast. You will get what you
want by just using the RTSPClient.cpp methods for the RTSP
signaling and otherwise treating the stream as raw udp i.e
just like multicast.

It can be done, because I've done it (admittedly with mplayer).

I just failed to subsequently make the received stream play in
a stable fashion.
