Like xs650 said, all digital cameras are sensitive to IR light (the ccd is more sensitive to the lower end of the spectrum). All digital and video cameras have filters to "fix" this, and have been getting vastly better in the last few years. Thats why those straight to video titles which you sometimes watch alone at night seem to have a different color balance (more green) and veins can often been seen through skin (hotter than surrounding skin, especially on the actresses which perform in various states of undress in all kinds of conditions = lower skin temp)
I once demod an exceptionally sensitive video camera which saw through thin clothing (in night mode), especially thin, blak dresses. The clothes looked like a shadow, and you could see the skin and details underneath. The camera was just a standard model you can buy in most stores
(should of course be called PVC Pervmaster3000)
To answer the comment about the servos, complexity is avoided as possible, you would need wiring for each servo, a power source for the servos and probably a few other (probably needing more power conduits etc.)
Another thing, Weight!
The cost of sending 1 kg of payload into space is around u$5000 on the Soyuz system and around u$10.000 on the shuttle.
I think that might also be the reason for not having a well stocked maintenance facility onboard.
Click the links first, functionality of the software is explained there.
Motion capture needs points of reference on the target. Its also usually done in a high contrast environment (similar to blue/greenscreen but not as fancy) and the reference points have to be highly visible on the target (i.e. white tufts on all movement points, black suit underneath). Most ppl wouldnt want to bother with this even if they had hardware/software capable of doing it....
As another poster pointed out, iTunes is the software/frontend for the iPod, which is why iTunes is available for windows, Apples main competitor. Only to sell more iPods, not philanthropy, as some seem to believe.
That should be the same rationale as for porting it to Linux, sell more units, sell more songs, cater to the widest audience possible.
I think the above poster may be right, in that Apple wouldnt make money of the program and song sales, but they might sell more iPods, as Linux users are now forced to buy mp3 players from other vendors, and the iPod is really really shiny and pretty.
I would think the porting wouldnt be too hard, as MacOs X is BSD based (admittedly Im not an expert). The packages might be more of a hassle with the ever changing environment but wouldnt it basically be enough to support a few distros (the "easy" ones) with rpms and the likes, the Hardcore users could probably make it work with their custom Toaster/Dryer Linux anyway, twiddling everything manually for fun and aggravation.
If Im just missing the point, dont hesitate to inform me (oh wait, this is/.;)
Perhaps not efficient use of money, but then research/testing rarely is.
I reckon the actual project is probably not worth the money (campus train) but the outcome MIGHT be worth it eventually
my 2cents
