I'm surprised they don't have more information available up on their site. It's pretty sparse to say the least. It great that the guy has gotten this far in his home-spun effort, but a lot more attention should have been put into the web site. And once he got close to actual manufacturing, he really should have gone and put up a request on Kickstarter to be able to buy more than the initial manufacturer's minimum production run (usually 3000 to 5000 units from the Chinese OEMs I've talked to).

At a minimum it has to support HID if it works like a keyboard in some certain mode. HID would also be the mode to use for a game controller, so the documentation shouldn't need to be very complex. I don't think a dedicated library supplied by the hardware guy would necessarily be needed either.

The Zeemote, another BlueTooth gaming device, has been available for quite a while and so far I don't think there's anything on the iPhone that works with it. This is gong to be an uphill battle - and the iControlPad guy really needs to reach out directly to indy game devs first.
