Absolutely! I didnt mean to derail from your main point. I've worked with LaserMotive so I'm reasonably familiar with their technology. You can make a ping-pong ball hover in an upward column of air, but I wouldn't call the ping-pong ball a UAV. It's just semantics, but I think the term implies a certain level of autonomy. Another example, there are many radio controlled aircraft in the hobby world that I would not call UAVs. One could take the same r/c vehicle, integrate an autopilot, and then UAV might be a more appropriate term for it.
