Quite interesting and nice. A bit delves into a "mass surveillance" like theme though.

Would be great to have some sort of local-only RF synchronization between the devices to "confirm" these events and issue alerts without requiring any connection at all...

P.S: Local-only RF synchronization, as in accelerometer and gyroscope data encoded directly (analog) 2.4ghz signal.
