Very nice idea, also prevents a huge number of the same aircraft addons. Let people 'sign in' on a particular type, that way the overlap between modders/modellers is minimal. This will lead to more types of aircraft being modelled, so we can also enjoy for example Italian WW2 aircraft, instead of having a mass of Mustangs and Spitfires, which will all be basically the same.
