I took out both filters: one large piece of plastic in front of camera and the other built-in coated glass filter:

Hmm, microcontroller reads several bytes directly from camera using standard I2C bus. These bytes contain an inforamtion about coordinates and brightness of spots. What to do with this depends on project, here I just sending them to PC for demonstration via RS232.

>Looks great! What software did you use, and did you modify the wiimote??

Yes I did modify the wiimote slightly:) take out the IR filter and remove camera from the wiimote. Of course it requires complete disassembly of camera.
I use my own software as I do not use Bluetooth to communicate with camera. However if one only remove the filter it is possible to work with any other software. My aim was to use this sensor in stand-alone devices without the PC, this is the reason why I am not interested in going through communication via unknown (at least not documented) bluetooth stack.

Project Ideas / laser tracking applications in stand alone devices

like distance or angle measurements. With Ir filter removed it is possible to track up to 4xN points, where N is number of cameras working at different wavelengthes. Proofs of concept are here:

Laser tracking? Yes, it is possible:

and it is operated at 200Hz via I2C (not bluetooth) what is convinient for stand-alone applications.
