No really build it myself. First, we need a prototype to develop our software on it. The proto can be any ARM based card plugged to a screen. We're currently playing with a beagleboard and an igep 0020 card. We can can plug an USB wifi and a USB IR receiver to play with (may be a home theater remote like this [1]). Then, we'd need to field test our device. This could be done with netbooks or small tablets, but not with a bunch of boards and wires ;-) . We'd need ~ 10 of them to lend to family and neighbours and get feedbacks. Once this is done, we'll need a small serie (~ 100 depending on price) to really get serious. Regarding the device, we'd need something quite standard. The screen should be at least 800x600. Bigger would be better, but the device price for the small serie will be the main limiting factor. Regarding user input, I'm wondering if a touchscreen would not be better than buttons behind the frame. Navigating in a menus with these rear buttons is not user friendly. But buttons are needed in case customer loose the remote control. May be a touchscreen as a fallback is better for users.

That would be better: I've not done HW design for a while (~ 20 years).
