To be honest, I've had the best luck with microsoft terminal services in so far as the thin client area goes - I use my XO day to day with my school's remote desktop server and it works flawlessly - the fonts are a bit tiny, but it works with no noticeable speed difference between it and a desktop. Why wasn't this approach considered instead of putting XP on XOs?<br>

I've just tried this. Ran x11vnc -viewonly -shared -forever on a Debian<br>
desktop, 1600x1200, and used krdc on a couple of XOs. In high quality<br>
mode, krdc repaints took up to two seconds when a major screen change<br>
happened. But in low quality mode the repaint was about a fifth of a<br>
second. So I have not reproduced your "once about every one second".<br>
<br>
You are using point to point networking. As long as the bandwidth of<br>
the shared medium (the RF) is not hit, then it should continue to scale.<br>
The bandwidth depends on x11vnc options chosen, and on what changes are<br>
made to the teaching image. There are ways to specify to x11vnc what<br>
bandwidth to use for the clients. You should only need to add the right<br>
option to ensure you do not fill the RF bandwidth. See the -speeds<br>
option. 4619 lines of man page. Wow.<br>
<br>
There's an opportunity here to look for ways to multicast VNC updates.<br>
I'm not sure of what is available for this.<br>
