Almost.  To play *incoming* H.264/RTP streams using VLC (or some other 
client), there need only be a "H264VideoRTPSource" class.  (You would need 
a "H264VideoRTPSink" only for streaming outgoing H.264/RTP streams - e.g., 
using the LIVE.COM RTSP server implementation.)

To stream H.264 video from the Darwin RTSP server, however, you will need a 
properly 'hinted' ".mp4" or ".mov"-format file.

As noted above, you will need a "H264VideoRTPSource" class.  To implement 
this, I suggest using "H263plusVideoRTPSource" as a model, and follow the 
H.264 RTP payload format Internet Draft that you mentioned.

Alternatively, if your company is interested in paying for me to implement 
this (and add it to the LIVE.COM library), then please let me know (by 
separate email).
