Well said! And for what is worth, I agree with you. 

Having said that, it should be possible to add code to OpenH323 to
prioritise audio over video so that people on low bandwidth connections
could still get some video without crapping all over the audio. 

To me, this sounds to me like a good last-year project for some student.
But from the emails I receive, it seems that most students are
hard-pressed to even compile OpenH323 for their final year project, let
alone make code changes. What on earth do they teach students these days ?
