Well, the coil idea is a good one, except that anyone worth their salt can probablyput it back (not like the coil is hard to find) and it'll be a PITA when you need to GO somewhere.
Here's my idea... make a relay that uses a magnetic reed switch, which will allow to mount the switch BEHIND any panel in the car, and will not require a visible switch. With this device, you can just brush a magnet past it, and it will toggle. Anyway, run the relay to the fuel pump and the coil. That way, while the engine might crank, it won't have fuel and it won't have spark. It might even be worth it to run a kill to the starter, even on the same circuit. This creates a multilayered problem for a potential car thief, and given that the switch will be entirely hidden behind an interior panel, it will be VERY hard to steal.
The reed switch idea is not new. I found a writeup on it somewhere, possibly off this site, though the author only suggests that it be used as a fuel kill.
