A friend of mine just got an Infinity FX with the keyless entry and start "intellegent FOB" thing. Where you can walk up to the car, and as long as the key is on you, you have full access + the ability to start the car by just turning a (knob?)...

I was wondering if anyone knew of an aftermarket system just like this that can be swapped into any car. Like a universal keyless entry/start kit that does the same as all the other ones on the market.

that would be cool, i think. what do you think? or
