I thought you could actually see control surfaces responding. I know flaps are displayed, but now I'm intrigued.
In theory, the code for reading/sending headposition could be a single value, and I'd tend to think that wouldn't be a huge burden considering this game doesn't even need a broadband connection.
Anyway, I like this idea. I wish the little pilot monkeys didn't disappear at such close range. No matter how cool the planes are, it's always going to look a little silly to see no people in them.
