Well, let's see.

16M color support would require 3 bytes per bit, and at 786432 bits
per screen and 30 frames per second that is 70,778,880 bytes per
second.  The MPEG advocates will try to convince me that they can
reduce that by an order of magnitude, so at 7,077,888 bytes per
second, that is hypothetically possible from a strictly network
bandwidth point of view.

To decode it in real time, however, and display it, would probably
require a very very fast machine...

Lower resolutions might be much more workable.  Conventional television
is much lower resolution than 1024x768.
