fobs, remote controls, and other unlicensed wireless devices. Ignoring
the interference, just hearing the beacon more than about 20ft away
will be a challenge. Driving all over the town looking for the beacon
xmitter is futile.
2. The Google Earth display zoomed in to the Street View and showed
the specific automobile where the mouse was hidden. Google Earth is
not real time and will only show a car that was parked there when the
Google camera van drove past, perhaps months previously.
3. The SIFT-III GPS receiver mentioned is probably a SiRF Atlas-III
receiver.

These are quite sensitive, but doesn't work inside the vehicle trunk
unless the body is fiberglass.
4. Assuming luck is with you, and you perform an amazing feat of
tracking the perpetrator to a parked car, what are you going to do
next? Break into the car to retreive your stolen laptop?

433Mhz transmitter that belches short bursts of NEMA 183 every few
minutes? It can be done with proper DF hardware but it's not easy.
I probably wouldn't torch the car. However taking the air out of the
tires might suffice. Eventually, I want my laptop back because like
laptops everywhere, it's not backed up.
Ummm... what insurance company pays in less time than the battery
inside the GPS Mouse will last?

"Lost" and "Prison Break" (just to mention a couple of what I call "too
much magic" programs).
Regarding the latter, I found one episode especially remarkable, when
they managed to break through a concrete block wall into the bad guys'
"impregnable fortress" using a magnetic device powered by--get this--a
couple of automobile batteries.
