I already have 2nd pc, it was my old pc pentium 4 3.00 ghz with 4 gb ram, acceptable ati vga card. So it will cost nothing to build up a new pc. Plan on playing 3 instance on main pc, and 1 or 2 instances on the 2nd pc.

I was looking at vetra kvm and Kb broadcasting, altogether will cost around 700$ which for the game is a bit too much. perhaps someone here has cheaper option - in terms of hardware configuration.

About software configuration, if I have 2 keyclones, how can I link the 2 pcs. Needed advices.
