I thought I read that the ir-leds are angled slightly outward. Perhaps the amount of light detected from each is affected by the angle, which could be used to solidify the position?

Hi , is there any way of using the ir sensor bar with the wimote in pure data?
yes, that is possible. the sensor bar is nothing else but two groups of ir-leds, that are used as a reference point in space. you couls also use a lighter (or up to four) instead. the wiimote just sends you the coordinates of the reference points' (ir-led, lighter, whatever) projection on the wiimote's intenal ir-camera.
Is it posible to track the movements of people carrying wimotes in real space with puredata?
no, that is not quite possible with the sensors, that wiimote is equipped with. it has 3 accelerometers (x, y and z), but it is very difficult (probably impossible) to calculate a position out of this data. it would be possible to calculate the position with the data from the ir-camera, but then you would need at least 3 reference points and they would have to be always visible for the cam. since the angle is quite narrow, it is probably not too suitable for position tracking.
