What real estate agents are doing is visiting a property to take still and video, inside and out. They take that back to the office to give prospective buyers a "virtual tour". Some of these virtual tours are posted on the real estate broker's web site. An RC aircraft will certainly facilitate this.

The RC aircraft community is taking advantage of blue tooth technology to connect the pilot to the aircraft. Eliminates the old issues of two pilots on the same frequency with two aircraft and causing expensive crashes. Not too hard to move from short distance blue tooth technology to Wifi and cell phone connection. But I think what I described in the first paragraph is what you have heard about.

In high tech, change is constant. There will be more new stuff tomorrow.
