Is skybook hooked up with anyone else?

I like their horse wagering platform, does anyone else know of other books with the same platform?

Betmania ?

I think I heard they ran into problems with RIO hotel in Vegas, and canned that name, so they are pretty much alone, connection to Mania seems to have never been fully answered, to my knowledge.
