BlueProximity helps add a little more security to
the desktop. It does so by detecting a certain
Bluetooth device, most likely a mobile phone, and
keeping track of its distance. If it is moved away
from the computer and the distance is above a
certain level (no measurement in meters is
possible) for a given time, it automatically locks
the desktop (or starts any other shell command
wanted). Once away, the computer awaits its
master's return: if the device is nearer than a
given level for a set time, the computer unlocks
without any interaction (or starts any other shell
command wanted).
