I'd like to see something like this also include a Tic Talk kind of phone, the sort where numbers are pre-programmed in by the parents, and which the child can only ring according to rules set out by the parents. When they were promoting this in Australia, they were looking at also having certain areas set as out of bounds and the phone would automatically secretly notify parents by phone, if the child strayed out of bounds. The parents could also go online at any time (via password access) and look to see where, geographically, the child was.
of course, a kid could beat this by taking the thing off, but that would also defeat the purpose and be easily found out if the parents rang and there was no answer.
We have the technology. It's just a matter of putting it all together. Soon we'll be able to also incorporate a small camera as well, so when the parent rings they can see from the background exactly where the child is and what they're doing.
Big Brother may not be watching, but Big Momma sure can be!
