There's already technology that does this, it's the parents responsibility, not the governments.
Besides, kids will figure out how to bypass whatever you do and tell all their friends how to do it as well.
Total waste of time.
Worse yet, if you tick the little brats off they won't show you how to use the remote control for your TV and DVR the next time you can't figure it out.
