Looking through the camera files, this mod looks to use bonnet, pod, cockpit etc when looking at other players in multiplayer. Good idea. You are limited to using the cameras in this mod though, unless you do the same code work with the cameras you'd like to use.
Having said that, it looks like other's work has been used in this mod, though I could be wrong. Again, translation is not the best and OP should provide more info and credit or obtain permissions before this disappears, it's a very good idea.
