Much as we hate to admit it - this technology is going to change the face of aerial work. Industry is looking to cheaper, more efficient, and probably safer, ways to undertake aerial photography of several types, remote sensing of various kinds for agriculture, fire surveillance, traffic surveillance, animal tracking and counting, and others. Not everyone will become licenced for very small UAV's. I'd expect more and more of them to be imported, regardless of any government efforts to prevent it.
happy days,
