I haven't looked into Plan 9 much, but I assume that the device driver
situation is at least as bad as that for the BSDs, probably worse?

Well, I used NetBSD and it seemed very complete, simple, and clean.
(The interface is clean anyway.)  Linux, on the other hand, seemed to
support more esoteric devices, but things were often inconsistent,
incomplete, and buggy.  Plan 9 is very clean, but limited and
primitive.  (More monkeys needed.)

The 'X/video/audio server' would be the terminal, not the CPU server.
A small quiet box that you plug into Ethernet, and plug in a display
(CRT/LCD/DLP/plasma/whatever).   No disk, boots from PROM.  An X terminal
that is fast enough to display TV/movies at 24-60 fps.  (e.g. it has to
decode mpeg2ts)  Or a media bridge like the Roku HD1000 (no longer sold)
that also does X11.

So, it is called a server, but it only serves itself?  Or does it
serve video to the screen?  I remember X uses weird 'server'
terminology.  But I understand now what you mean.

For your CPU server, if it has a spare PCI slot you could plug in
a OGC or OGD card.  You would need a device driver for Plan 9.
Whether this would do what you want?  I have no clue.

Right.  It would do it... but would it be fast enough?

By the way, the whole idea of serving video in real time over ethernet
is moot if latency is a problem.
