Thats cool.
I'm wondering though, lets say that someone purchases an F18 module and joins a server that also knows about the F18 module, that person can then fly around in his F18. However, if someone who does not have the F18 module joins, would be possible for them to see, but not fly, the F18?
I'm just wondering, because imagine if a server has multiple modules installed, it would be a bit of a nightmare for other players who do not have all the modules to have to go and purchase them all just to play. I'm worried that multiplayer could become a bit fractured because of all the different installations combinations possible.
My solution would be the ability to download a 'free' version of the module that only contains the models so that other players can see them in game.
