I had the same thought in about June, but decided it wasn't worth pursuing since you would have to figure out how to recover it and that's assuming it doesn't get snagged on something or stolen. About the same time someone announced a GPS received + GSM transmittor for shoes for dimentia/alzhimers patients, the would require close proximity to a phone network, which may not be as much of an issue in other countries as it is here. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
