Right - now, how this is implemented is another matter entirely;
e.g. how you do reliably determine that the input device at the
sysfs path /sys/class/input/event3 really stems from some Bluetooth

We already do this on HEAD :-)

Probably s/bluetooth/bluetooth_hci/ to clarify. Patches against
HEAD for more properties are welcome :-)

You must be talking about some of the code on HEAD.
