It seems that a few bad drone pilots are causing problems for all of the good actors in the system. Since there is so much potential for injury, and since it only takes one terrible incident to bring down stiff regulation on everyone, perhaps drone piloting should become a licensed activity or sport.
Establishing drone pilot licensing would theoretically ensure that legal, licensed pilots are aware of the risks and are willing to assume greater personal liability in the event of operator negligence. The hobby would gain legitimate legal grounding and become less "cowboy" more or less overnight. I can't imagine it would be remain crowded with careless risk takers.
If this is done early, before any major incident or bad press, the FAA won't have to step in and put more rules and regulations in place. If there are to be new rules, I imagine that they wouldn't be nearly as overbearing for a well-behaved professional hobby that doesn't needlessly put health and lives at risk.
I think professional hobbyist (not an oxymoron?) drone pilots should lobby lawmakers for something like this to take place as soon as possible, before the FAA starts making mandates. I can certainly see the FAA's concerns--there is legitimate risk and danger. Something will eventually happen that brings the entire house of cards down. If the drone pilots don't ask for this self-regulation themselves, I wouldn't necessarily be against the FAA moving ahead on its own.
On a personally related note, I'm involved in hobbyist high-wattage laser projection for making video games and interactive displays. (I think there are videos linked from my HN profile). The entire lasing community cringes when there is news of some idiot shining a laser pointer at a plane or when someone is caught using a high-wattage laser for destructive purposes. It's a seemingly regular occurrence, and I'm pretty certain there will be regulation coming down the pipeline eventually. It seems there is no shortage of careless ignorance when it comes to dangerous hobbies.
