Although I've never done it, you can pair a BlueTooth controller to an iPhone and use it as an "assistive touch" device to control the cursor and operate an iPhone. Someone should order one of these things and see if it can operate the Cab 3!

I wonder if one of these would work. I could see using the iphone proper for most things, then use this widget to control your current train and getting a few key buttons for speed, dir, horn, whistle, halt, etc...
