This is exactly the sort of thing I hope the FAA regulates. Multirotors now still have a very bad track record for long-term reliability, and even any-formfactor remotely operated air systems have been advised not to fly around densely populated areas for fear of harming someone. And you want to fly these vehicles not only in densely populated (residential) areas, but in and around disaster and emergency situations? I can see it being used as a tool by emergency response, but if I was a first responder and someone did that on my site I'd do what I could to get it down and stopping endangering everyone present.
