Neat idea, but it seems to me that you absolutely must hide the backup key on your property for this to be safe. There are way too many points of failure between the phone and lock. Why not have the phone talk to the lock through the local wifi? Or put a wifi/bluetooth radio right in the lock? That should be more dependable and faster. Is that what you are talking about here? "if you would like to access Lockitron only via your local network, then we welcome you to flash your base-station with a new image that gives you full access to develop as you see fit (coming soon)" Or, you could communicate via QR code on the screen, using a camera in the door (that doubles as a remote peephole). Or, you could encode the data as high-frequency sound and use the speaker/mic for two-way comm. There are all sorts of possibilities that beat going over the internet.
