I don't know of a way to do that accurately, since you can't rely on the 
timing of the signal due to walls, etc.  You could tell of a bluetooth 
device is within range or not pretty easily.  Maybe it's possible by 
triangulating, but still seems like it would be very inaccurate.  Maybe 
bluetooth isn't the right way to tackle it, and instead there's a 
different technology that you could use (RFID?).
