[magnate]

I have exactly this arrangement - I run a dom2 graphicless server in the background on my linux router, and I connect and play my turns from my Windows box. It all works fine. My router is an old Pentium 233MHz, and it takes about 45s of CPU time to host a turn (we're on turn 43 so it's pretty busy). It uses no resources at all the rest of the time though (apart from a tiny amount of i/o when a player connects or disconnects).
