What's involved in transforming a rooted Android device (in my case, a Nook Touch) into a real HTML5 kiosk?
Meaning: The user never sees any part of the Android OS GUI elements; the screen is always just a full-screen browser window located at an HTML5 app. When the device has to go to sleep, it doesn't change what's displayed on the screen, and when it's woken up the user is right back in the HTML5 app.
