Well I need something like 5-10 fps. An issue is the comression
method: MPEG and friends aren't good (I think) for compressing stuff
with sharp borders. Maybe I could use A sequence of PNG images, but it
isn't a great solution.

Well the bandwidth issue is most of all related to  video compression
(see above). Well maybe 256 kbps would be nice.

It should just show what's happening.
