As Brian explained it to me, these are radio frequency cameras. He'll give them to teams on the water and receive their short-range video on shore, putting it straight onto the event web site. I think he said the tiny cameras will be in ball caps, to be worn by volunteers. Chum up to the guy now, folks, 'cause I think what he's developing has such a wide application that it is only a matter of time before he's "discovered," and we'll all be shirt-tail cousins at best when he's in Hollywood...
