BTProx is a simple app for Windows PCs that lets you take advantage of the most basic function in any Bluetooth session - the ability to detect a device.
Load it up under Windows 2000, XP and Vista with a suitable Bluetooth device - either built in or a USB dongle - and pair your PC with your phone.
BTProx will check to make sure your phone is within range. if it isn’t, it will activate your screensaver to lock your screen or optionally run the program of your choice.
Maybe a bit on the paranoid side if you are sitting at home, but if you work in an open plan office you might wish to conceal the open Pocket Picks RSS feed on your screen when you nip to the loo.
BtProx is free and open source.
