I have know these guys for a few years. I met them as part of a UAV challenge DARPA was putting on. They already have a working prototype and are in the official Apple accessory program! The radio is going for $99 bucks as part of the fundraising campaign on Indiegogo.

We will be hacking on the ground station at the NSMeetup hack-o-thon March 30th at Sincerely in SF. http://www.nsmeetup.com/events/103975442/
