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.
