I believe Netscape for X allows some sort of video/audio reception; but
since their site is completely unreachable this morning, I can't work
from anything but memory. That's a pretty specific solution to the
problem, in any case: only works if everyone is using one particular
browser/windowing setup.

Then again, this isn't TV -- maybe refreshing the page while the user
just sits there isn't such a great direction to take.
