Don,

Thanks for your response. I've been mulling this over for a few weeks now,
trying to figure how to slim this down even more. I was thinking of
something as simple as a USB access point in the car, with a script to
detect when its mac address showed up on the network.  Problem there is one
you've already identified:  You need some sort of uptime to tell the
difference between an arriving car and a starting car.

This is very interesting to me, and I'll continue to persue it and let you
all know what I come up with.

Anyone else have any ideas?  Wifi instead of RFID.. the $500 cost savings
have me drooling.
