You can try to contact xNurbs guy directly too to show interest.

I don't want to paste the reply I get here, but to summarize : It's easy to do (would take a few weeks to prototype), 'they' would need Michael help. However they are concern with the community reception about the price, an other funky concerns about how to educate the correct usage of the product (?¿).

Also I think they don't support Mac, it's unlikely to happens.
