I am looking for examples of someone that has done a "rubber"
pour-in-place floor that is typically used in gyms and running tracks
such as:

http://www.sealmaster.net/catalog/sport_track.html (Track Master)

In a residential home or something even close to that.  I am also
looking for companies that sell this type of product in DIY quanities.
 If anyone has seen this and could provide an opinion on the
suitability for home use would also be welcome.

But for the money I am looking for a documented example or someone
that has personal knowledge of living with such flooring.
