Motion tracking SOFTWARE isn't the problem IMHO, it's the Hardware. You need 2 high resoltuion hispeed cameras that can be synchronized. You will then use some markers that will reflect infrared light. The software will then recognize the various markers and extract the bones animation data.
But probably you'll be able to do it with some simple webcams and a bitz app. But yu still need to be able to record from 2 cams at the same time. A cheap solution could be to use 2 PCs. you would then record 2 movies, then copy both movies to one machine and use some sync tags in the background of the movies to sync them. The you only need to do some Readpixel and 3D Math to extract the animation.
Of course you need some highly reflective markers, they are used as protection clothes for street workers etc. and some infrared spotlights, used for nightvision and night video recording.
you could also create markers of coloured LEDs, this would make it easier to recognize the various markers logicaly (what's feet, what's hands, what's the head etc.). it's only important that the markers can be seen from most perspectives.
