My experience of serving a Windows desktop to a plan9 terminal
is that TightVNC with the DFMirage "Mirror driver" works really well.
I've had responsiveness issues when the viewing machine hasn't
enough CPU power to decode the screen data in real-time. A lot of
power seems to be needed, my PDA, a 416MHz ARM can't cope with any
compression at all, I have to limit vncviewer to copyrect and raw
encodings only. Encoding doesn't seem to need half as much CPU
power. I ran Xvnc on a headless server with a 400MHz AMD K6 with no
issues that I recall.
Now I don't have any expertise with VNC, but decoding anything, is
supposed to take less time than encoding it. I would check into that.
All that gear was using either TightVNC or the plain vnc-
x.y.z.tar.gz from RealVNC. When using Vine Server on a 466MHz Apple
screen updates are not really adequate, while the mouse pointer
lags if I use the VNC server supplied with OS X Tiger on the same
machine. x0vncserver is a known problem server which I haven't used,
IIRC it basically works by taking screenshots continuously and
sending those.
