Votes for Registration. Whilst a lot of people mean well when coming up to me, I have been distracted by the odd idiot that want's to debate me on how I'm breaking the law. I fly everyday I can to learn all I need in any given situation. The drone is not a toy - well not this one. If you begin to fly everyday like me and in different places, you will know what I mean. There is a huge amount of paranoid people out there and they distract me quite a bit - I've had one person drive up the gutter and headed straight for me in a Public Park.
Definitely bring in license, I will use it and then politely tell them to Move On and let me be about my business. Licensing will bring a better understanding to the community with such control, that instead of thinking every drone is gazing into the open double bay doors of the shed - instead they may see these drones actually serving a purpose so diverse that they would like one themselves. More drones in the skies will require some kind of certification.
How strict the licensing becomes will depend on today's operators.
There are simply too many people out there that would not even care to look up what the rules there are. A large percentage of those types would only require a few clowns to create even tougher laws, other than simply being registered.
Whatever Dave ... I say bring on registration sooner than later. I could use it to make others understand that they're not being spied on and or no one is going to be seriously injured. There are good reasons people shooting these things down.
Just make the licensing affordable and keep recreational use on the drawing board, where local councils could pass their own by-laws.
It's not unheard of for photographers to be fined. Even your everyday cameras have laws that limit their use.
With drone technology - Of course there is going to be laws.
