He probably had something in mind similar to what you'd see in Rogue Leader, the Star Wars game for GameCube. If you've ever messed with it, you can fly the ship from inside the cockpit, and you can also use the secondary control stick to look around inside the cockpit (which means you can look to your left or right, above and sometimes below you without actually rotating the ship, from within the cockpit). Its a nice idea, but I don't think FreeSpace 2 would support it very well. (Especially considering all the additional cockpits you'd have to create for every ship.)
