My cousin uses a commercial drone in which I was interested. When I mentioned this to him on Saturday, he said the makers of the commercial drones are moving toward FAA exemptions. Trimble apparently has already (recently) received an exemption from the FAA.
He pointed me to this new bulletin: http://www.trimble.com/news/release.aspx?id=121014a
He also said that most home inspectors will not be using Trimble products due to their limited use of drones (only a few minutes per day at most). Really only practical where they can eliminate significant labor hours. None the less it appears the FAA is willing to work with some commercial drones. These units typically I would guess work in large more rural areas though versus high density urban areas.
