This strikes me as a terrific idea. The whole reason I'm interested in RFID
is to know if my cars are in the driveway. If both are gone, temperature
adjusts, doors lock, roomba vacuums... etc.

So I don't even need a small battery powered chip. It could be bigger. A MCU
with an off-the-shelf USB access point. Or one of the smaller chip
solutions, but not wallet-sized.

Anyone have any ideas?
