I put in the hooks for CUSeeMe to allow nv users to watch some CUSeeMe conferences that were being reflected onto the MBONE a few years ago. I later added the encoder support when it looked like CUSeeMe might start supporting multicast & RTP. However, that hasn't happened in the way I expected, so the encoder isn't really all that interesting. > Thanks for the patches.

However, they were first supplied to me in precomputed form, and it doesn't take much space to leave them that way... -- Ron Frederick frederick@parc.xerox.com
