Heya, this works great! Initially I couldn't get it to work but I've turned off AP Isolation on my router then it started working.
I want to add onto the discussion here about hiding the screen buttons. When I hide the buttons from the menu, the buttons that I've hidden doesn't seem to register. It's not exactly a hide feature but rather a disable. I would love it if there'd be an option to hide these and keep the screen completely black, following thundermin's comment about burn in as well.
