Okay, got it working. Only works in full screen mode, but is waaay faster the VNC on my 100MB lan at home, contrary to what I have read in other posts. Definately in the ball park with Windows terminal server.

Now to see how to reduce the screen resolution to 800x600 and to attach to an XP client.

Looks very promising. Hopefully NoMachines makes enough money on their commercial products to keep supporting the Windows client. Nice to have a couple free thin client options with Linux.
