Well, if you're not hooked into a single "unit", then buying a BT GPS
unit and a Nokia BT phone w/ internet connection or SMS. Write up a
small Python app to upload/SMS/Email the GPS position to a server and

Now, to be slick, each remote car could have a Wifi connection and use
signal strength as an attempt to be "differential". I would assume on
the playa there probably isn't much interference or multipaths.
