First I've heard of project Loon, sounds interesting. Is anyone familiar with the FAA implications of flying "anything"? Example, I presumably can go in my back yard and launch a kite on a windy day and let it fly a few hundred feet in the air (your average kid spool will give you 500 feet). I don't attach blinking red lights to it and I don't call anyone to tell them I'm doing it. Now, what if I got a balloon and floated it above my house with a wire going down. Assume I'm able to make the balloon stay up hundreds of feet for a few weeks despite weather and the weight of the cord. Also assume non-commercial, could I legally "just do it"?
