That's why it would need to be something new. Right now we have the "big pool" where you can have as much fun as you want, but you can also drown and there aren't lifeguards to help you out.

A rewrite of the OS to prevent apps from doing what they want would break a ton of existing app -- that just won't fly. But, a "new type" of app, something that's safe and you install from the AppStore...
