    This BlueTooth Proximity is available on linux since ages (well, known for a while as BlueProximity). I finally found it for msWindows, thanks for that.

    The linux version is a little more sophisticated however: With that it is possible to define a different timeout and ‘distance’ for both locking and unlocking. The distance is actually the BT signal level. And it shows the current level while setting them. A verry nifty feature, also for testing.
