Why would you want to have 2 people control 1 pc? If you are running xp and had 2 machines you can run the other with remote desktop. I mean you only have 1 mouse pointer,so who gets control? You can have 2 mice but they will oppose each other. Even with 2 monitors you can't have 2 perfectly seperate desktops, the mose pointer only lives in one instance so only shows up at 1 spot on 1 desktop at a time.
