    A guy from our local Amiga dealer told me about a demo he went to of the
A3000UX machines (equipped with CBM's 34010-based graphics card).  Several
stations were networked together, each with a video camera mounted above it.
Basically, from what I remember him saying, you could open a window at the
station you were sitting at and view another person's live image.  You could
then apparently send mail to that person by dragging an icon or some such
thing onto his/her picture.  People had multiple picture-windows open and were
conversing heavily...
	 Don't really know if this was done via ethernet or some other trick (the
machines were sitting close together, so I imagine it could have been possible
to have some kind of direct video connections between them somehow...).
	 I doubt there was any compression being done, as I don't think CBM is
currently working on any compression hw (would be nice if they were, though.)

	 The NeXTCube with the NextDimension board (when it gets here) should 
be able to perform similarly; if they get the MPEG chips working, it'll
also have compression capabilities.
