Attached Link: iPi Desktop Motion Capture Standard Edition

This new software on the Renderosity Store, iPi Desktop Motion Capture Standard Edition, selling for $900+ sounds real interesting.  Previous to reading about this software, I have never heard of such a program being possible.  does anyone know if Hollywood is using a similiar none-point type capture system.  Just put a video on your desk top and using the software and a few other goodies as listed, capture most any action?  Interesting.  There is not however a single photo capture or video demo of the software in action.  

If any of you have any experience with this let me know please.  I am real interested.    I assume Renderosity has tried out this software?  They certainly checked out my two little store items :)
