Interesting example: there's currently a major squabble in the British gambling industry over the use of drones to provide low-latency streams of horse racing. Off-track betting is legal here, as is in-play betting - you can place a bet right until the winning horse crosses the line.
The latency for a typical satellite broadcast is about 10 seconds, so several gambling syndicates operate their own drones to provide a private low-latency stream, thereby gaining a huge advantage on in-play betting. The drones are being flown legally in uncontrolled airspace, so there racetracks are at a loss as to how to respond.
