Neat footage and definitely some great angles, but I can see this getting expensive for us mere mortals 
Imagine a competition where the competitors all carry an iphone in a waterproof case. You program your self-piloting flying camera robot to stay in a certain range from the iphone with the lens pointed at the iphone. The robot just flies along with the competitor perfectly framed at all times.
I mentioned in another thread that I saw a sax player using an iphone as a wireless mircorphone attached to his sax. In the past you paid $4000 for wireless microphone systems. Now you get them for $36.
There is also some aussie guys that have been doing this as well. Some surfing footage has been on coastalwatch. Pretty cool stuff.
I went to a murdoch uni open day about this time last year and a young bloke about 23 years old made something like that. It had 4 propellers and had cameras in all of the gaps between the propellers. All up it had 4 cameras and he said he was going to start to sell them to the army. there was two sizes a small and a large. the large was 40 grand a pop
and the small one was about 25 grand. Very expensive but the graphics were excellent.
