Whoa, you’ve really been thinking about this :)
Looks like I have reference documentation right here. I’m hoping to get started on this in June/July. I’ll develop it as a mobile web app and then possible convert it to a native iPhone app (so it should work everywhere…. even on my WII!)
If anyone is really anxious and wants to create a visual mockup of what the app will look like – I’d be much obliged. Otherwise I’ll get working on that as a 1st step once my development schedule gets to this.
