Bart,
I'm still under the impression that a property owner holds use control of the airspace in and above their property up to a certain level. That may be between 200' and 400' AGL, IRRC.
that may very well be the case and even the FAA might not ever intend to try to regulate airspace inside of buildings but they did successfully change the definition of "aircraft" to include basically anything that intentionally flies through the air so I don't see how there would be a legal limit on outdoors airspace only. Theoretically if you are at a party and throw a cheeseburger at another guest you can be violated by the FAA for careless/reckless operation of an aircraft. Careless/reckless is basically the only regulation they can enforce at this point along with airspace violations.
