The point, as I see it, is that the only concern the government has with this issue is whether or not you are taking money for the flying. If you fly a drone for compensation, in their eyes, you are a commercial pilot. If it had been done for free, wihtout any form of compensation, they would not have an issue. You can bet that soon, very soon, the rules are going to spell this out. This primary fact will be what seperates the hobbyist from the "commercial ventures". As long as there is money chaning hands the feds (ie, FAA) will be planning to oversee this. The AMA is trying to distance themselves from that form of flying as well. Having been involved with general aviation for a few years it is obvious it is all about the benjamins.
Fly crazy all you want. Do it while getting paid, and they will find a way to drag your hiney to court.
