We're going to get this great whiteboard software setup in a bunch of our classrooms.  We don't have any wiimotes at the moment, but we do have a bunch of USB IR receivers that were packaged with Audigy sound cards.  I know this whiteboard software does not support them, but with driver support aside, is it possible that the IR receivers themselves have the capability to do IR tracking to the level of the wiimote?

The Wii Remote is more than just an IR Reciever, like the one in the front of my laptop.  It's actually an IR CAMERA.  In fact, it's even more than that.  The Wii Remote is a camera that is able to distinguish the 4 brightest sources of IR light and calculate them in real-time, then transmit the positional data over high-speed bluetooth connection to a computer.  This means I can mount the Wii Remote 15 feet away from my computer and collect data that a hobbyist can plug into an application.  There's no way you could ever do such a thing for less than $40US.

IRtracking can be done with modified webcams and some imageprocessing.

If its cheaper or easier - I don't know..
