Two players connected to the same game computer

Question

I would like to know whether there exist games running on one computer but collecting input from two players using each a mouse or joystick connected to the same computer?

If they exist, how does the game keeps separated the data from the two mice/joysticks?

Thanks in advance, Stefan

Well, this seems to be similar to what you want. Teamplayer3 allows multiple mouse pointers at the same time: http://www.dicolab.com/products/teamplayer/

That is on windows. On *nix, check this project: http://www.icculus.org/manymouse/
