I have a question, does anyone know of a way to run 2 instances of a game with some sort of key broadcasting software but having the 2 instances of the game running on 2 separate computers?

What I have:
i7 920, 6 gigs of ram, and a nvidia 245 (more than enough to run multiple of anything)

and

pent d dual core 3.0, 4 gigs of ram, 8600gtx (plenty enough to run 1)

Setup now:
Main monitor is the i7, connecting to the pent-d with Input Director(similar to synergy, software kvm(well no Video really))

What I want:

Run 1 instance of warhammer on my i7 pc and more or less a heal bot on my second computer without having to go hardware kvm, the fact of continually changing focus from one screen to the other kinda sucks. So I'm looking to see if there is anything out there that either integrates with synergy or other software kvm, or if there is anything that is able to broadcast the keys cross computer...has anyone looked into this?

If I didn't make my self clear enough, I shall elaborate, but any help, love, or pointers I would love.
