Red tends to bleed very badly so generally its avoided.

The eye is MOST sensitive to Blue. so video compression schemes throw away (compress) a lot of the blue in an image. This makes it a very poor candidate for chromakeying.

That leaves green as the only real choice left.

I wish I had known this a while back. Wasted hours of footage using a blue screen

I have seen a fantastic product which is a cloth made of small glass beads. it reflects green light. the camera is then fitted with special LED's around the lense which illuminate the cloth and nothing else. the result is near perfect chromakeying.

I cant recall what the product was called but it wasnt cheap.

A quick search failed to find it. but its out there somewhere
Ooops found it. Chromatte!

I just checked out the product you mentioned and that is some crazy stuff... not quite sure I would spring for that though... I'd have to see it in action.
