iPad as CarPC/Digital Climate Control
I had an idea. I did a little searching. I had another idea.
Let's start with this.

Basically what this is, is a wifi connected iPhone running an app to control an arduino controller to handle the lights. I thought this would be pretty cool to have in the vr-4 so you could essentially have mood lighting. I thought this would be cool to have for like drive-in movies and such. Then I thought about having an iPad as a CarPC. It basically has all of the functions a car-pc needs.
The iPad is
Height: 9.56 inches (242.8 mm)
Width: 7.47 inches (189.7 mm)
This would have a conflict with the DCC. Then I thought about removing the DCC, and using the existing arduino controller to talk to the DCC controller and have the iPad act as the controller. You could even write the app to have the screen images that you would normally have for the DCC. Even the buttons!
So, I am asking, how difficult would this really be to accomplish? It can't really be that difficult to write a program that can handle this for an iPad would it?
