I first saw this story because they call it a 'papa-momma surveillance system' - which I thought sounded funny, so I clicked the link. The story is from Mumbai, India and it appears that the idea for this 'solution' came in response to a recent sexual assault on a 3 yr old during a school bus ride.
While I think that their idea sounds great on paper, I can't see this being a viable solution at the pricepoint they mention (around $1500 total for each bus). Either Mumbai has access to some kind of spectacular wireless technologies that aren't available anywhere else on the planet, or the collective load of concurrent viewers should crush the system into oblivion.
Keep in mind that they envision the system as a live monitor, not to prove something after the fact...
Anyone have any thoughts on this 'solution'?
