These guys are kind of working in this: http://www.famigo.com/

Their approach is targeted at kids though, I'd love to see someone tackle the general purpose approach.

Sounds like a great project for someone with a lot of free time. I rememeber hearing that the guy who came up with what is currently the ios notification style was hired by Apple after his jailbroken hack.

The void is wide open for someone to solve this well and be rewarded for it

I have heard many, many times from parents whose kids play with their iPhones, iPads, etc. that they would like to have this mode where only the current app is active, WiFi is disabled, etc. Kids are quick to figure out how to buy extra stuff from within the app.
