The Q-Zone

Here's an idea that's not going to work: a company called Bluelinx is pushing a technology called Q-Zone that uses Bluetooth nodes to automatically put cellphones into "quiet mode" when they enter a specific area (like a movie theater, hospital, library). Besides the fact that so few people have Bluetooth on their cellphones here, the big problem is that for it to be useful on any meaningful scale the Q-Zone software will have to be installed on a significant number of phones
(the nodes won't have any effect on their own, whether a phone has Bluetooth or not), and we just can't see many people voluntarily agreeing to software that let's someone else control how their phone works (it's the same thing for that software that's supposed to be able to disable the cameras in cameraphones). Never gonna happen,
and there isn't much incentive for manufacturers to build this into their phones, either.
