Solution for docking iPad mini on a wall?

I'm looking for a solution for a wall-mounted dock for an iPad mini which is being used to control different elements of a home entertainment system for a client.

So far, I think what I like best is this agility case from Otterbox paired with one or more of their various docks and mounts. It looks a lot like I could mount their wall mount right next to a power outlet and just use keep a regular adapter plugged in all the time, or maybe figure out how to mount their power dock to a wall.

Ideally, there would be no cord for children to steal to charge their own iOS devices.

What're your thoughts? Has anyone found a great solution?
