Sounds like it might work pretty well.
A bit off by saying the infared sensors are for ALL tracking on the Wiimote...any motion control is accelerometers only, usually.
But their idea isn't bad...it is indeed a "niche" product though...something that precise always costs more...Wiimotes cost $40 for a reason, too. If the price went down and could be utilized in something like a videogame system...then heck, why not.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
