some years ago there was a toy-company called Zowie (bought by LEGO as far as I know) they had two products - a "pirate ship" and a "garden" where you could frrely move around some small dolls and their accurate position was transmitted to a connected PC - they did all the positioning stuff some custom chip included in the toy - so producing this stuff cheap in large quanitities is no problem at all
During the presentation Jobs mentioned, that you could for instance create presentations with scripts connected to your acounting-system to reflect your current numbers - so I assume Apple won't prosecute others for creating the files
i know tow systems capable of doing similar things - there's sivit (aka "virtual touchscreen") by siemens - a system consisting of a projector, a infrared source, a camera and a pc with a framegrabber-card - if you put your hand on the projection surface the software recognises your finger and the mousecursor is controlled by your finger - the software is Windows only and the complete system is quite expensive. Much more interesting was a system i saw at SIGGRAPH 2000 - i think it was done by some students at the university of washington - it was using rear projection and was able to track more objects
