The AMA has some interesting information regarding the regulations the FAA is proposing for UAV's. While so far model aviation has been spared any new regulations, the story isn't over yet. The issues surrounding UAV's in the airspace is certainly complex, and while the main issue is safety of manned aircraft, other issues like privacy from aerial photography keep cropping up. Certainly something to keep an eye on this year.
