Hell, LaGuardia has ASDE-X installed. The fire truck in question did not have a transponder, rending a significant portion of the system pretty useless in this case.
It's unclear whether any of the ground vehicles at LaGuardia are equipped with the transponders, or at least it was unclear the last I heard.
Yeah, it's very easy to be "open" to the idea. I'm interested myself, but I know next to nothing about what the effects of that sort of integration would be.
