Windows has something similar built in. It locks your pc whenever a paired Bluetooth device (eg your phone) goes out of range

  There is nowhere I could go in my 2600 square foot house that would be far enough to cause my phone to go out of Bluetooth range of my desktop.

    Man, you're lucky. My phone goes out of range seemingly randomly while I'm standing in front of the computer.

    It probably goes by RSSI. You might not be able to get "out of range" to the point where the connection is terminated, but the desktop can (poorly) approximate distance by measuring received signal strength.
