No matter what we do there's going to be people complaining about privacy. They don't realize a guy in a helicopter or a plane already does it under the guise of national security. My take is notification. What if a couple days before a real estate shoot you put up a couple flyers on the surrounding neighbors houses and say here's what we're doing and you're welcome to come watch from a distance. We promise not to take pix of you or your house, and wait for feedback.
