This is precisely what I'm planning to do right now, as soon as my Sirf III Golux lands. (Plus, use off-the-shelf navigation for Nokias, such as wayfinder, etc. -- another option is Nokia 770, but it doesn't have GSM/GRPS/UMTS, just WiFi). Another thing I'd like to do is map GPS position fixes to cell IDs. > Now, to be slick, each remote car could have a Wifi connection and use > signal strength as an attempt to be "differential".
