Weather-proof pet doors with a camera and wifi connection so you can remotely unlock/open or lock/close the door. Better yet, a camera with pet recognition software. This way you only let in your pet, not the neighbor's kitties, not the raccoons or squirrels. Should have the ability to recognize at least 10 different animals for approval. Maybe also have software that can tell you if your pet is in or out.
As far as I know there are ones that can respond to a micro-chip that you can place on a collar, but not a door that can allow you to say, deny going out because it's too cold. Or if your pet is near the door and another animal tries to get through, you'd want to stop that.
So far I see hobbyist stuff, but nothing really commercially available.
