From an Australian newspaper (of all places) a report on a British company offering parents everywhere peace of mind:
Parents in Britain can check exactly where their children are without having to phone them, thanks to a new service launched yesterday.The mapAmobile service can pinpoint a child to within 50 yards by using the signal from their mobile phone.
I think it is safe to assume that the technology can be applied just as readily to adults. Apparently, the recipient must agree to be traced by replying to text message but I bet that hurdle will prove surmountable with just a little tweaking.
