Multiple mouse pointers?

Question

Is there a way to accept input from more than one mouse separately? I'm interested in making a multi-user application and I thought it would be great if I could have 2 or more users holding wireless mice each interacting with the app individually with a separate mouse arrow.

Is this something I should try to farm out to some other application/driver/os_magic? or is there a library I can use to accomplish this? Language isn't a HUGE deal, but C, C++, and Python are preferrable.

Thanks :)

Found this multi-pointer toolkit for linux (it's actually a multi-pointer x server): http://wearables.unisa.edu.au/mpx/

Answer 1

You could try the Microsoft Windows MultiPoint Software Development Kit 1.1

or the new Microsoft Windows MultiPoint Software Development Kit 1.5

and the main Microsoft Multipoint site

Answer 2

Yes. I know of at least one program that does this, KidPad. I think it's written in Java and was developed by Juan Pablo Hourcade, now at the University of Iowa. You'd have to ask him how it was implemented.
