People like the GRASP[1] guys: http://www.youtube.com/watch?v=MvRTALJp8DM http://www.youtube.com/watch?v=MvRTALJp8DM are probably somewhere pretty high on that list. They still need to solve the location sensing issues though - having high-precision calibrated wall mounted sensors aren't really practical for ad-hoc use. I don't doubt that someone will solve this problem in the not-too-distant future though, and heavily autonomous quadrotor aerostats will be in heavy use.
