Fork-mount trainers? (Sportcrafters Omnium)

[whydobearsxplod]

I'm intrigued by Sportcrafters' Omnium Trainer (http://www.sportcrafters.com/products/omnium-trainer). The Omnium seems to be a redesign of their older Mini Rollers which used a separate fork stand and a very simple fan resistance unit. I suppose a similar setup could be achieved by using resisted rollers and a fork-stand, but I like the size and portability of this concept.

Any experiences with the Omnium or Mini rollers?

Are there other companies doing something similar?
