I, too, am extremely interested in vic supporting HD formats, (including 
One of the issues is the encoding latency problem. Not sure there's a 
nice low latency
software encoding solution out there yet. Alternatively, we might look 
at cheap hardware
encoders as the answer or HDMI cards to take the input from the camera. 
Can vic be made
to take the output of, say, the BlackMagic Design HDMI card on a Mac?

I am currently using AGDV under windows but would like to move to linux 
and use the
HDV/DV linux vic for the DV part; i don't think it's encoding the HDV, 
just accepting
it as input from the camera already encoded??? [chris?]

My ideal would be to encode the presenter's laptop output and deliver 
that as just another
video stream along side the presenter's video and the audience video and 
have autoplace
lay them out nicely in a framed window, a la Adobe Connect or similar 
products, so the
presenter, the slides, and additional commentary could be nicely 
recorded for later video
on demand playback.

Just my opinion (and need),
