I don't know too much about the Bluetooth protocol, but would random MAC addresses break pairing with non-apple devices? Every time the MAC changes, woluldn't the device need to be repaired? Another great win for Apple... make it hard to use non-crapple devicesAlso, some hardware suppliers like Apple allegedly randomize BT and WIFI MACs until the device is paired to prevent this sort of snooping. Hence the rise of in-store WiFi networks.
