I have a game that I would like very much to play with several users 
similtaneously. It is not necessary that the mac "think" more than one
mouse is moving the cursor at any time: only that each user have an
equal ability to control the cursor. I've tried simply creating a cable
the spliced four mice into the mouse port. This did not work very well.
the mac acted as though the mouse button was down all the time. The
movement of the cursor was also less pronounced than if just one mouse
were being used.

I've seen trackballs and joysticks working similtaneously on a single
mac, so I know something like this is possible. Does anyone have any
ideas? I will be in the market for 4 used mice/joysticks or trackballs if I
can get this to work.
