One would need to be able to have all of the players input their Heading, Pitch Roll & X,Y,Z into the online game players database and extract other players same data and then their computer could compute and render their (avatar, ship, whatever thing) and other players Realtime Position (avatar, ship, whatever thing) within the games 3D game model database from the game player's perspective. Potentially hundreds or thousands could play at the same time and their own computer would do the rendering of all of the images.
Sounds like a cool potential project!
Too bad I am totally swamped right now!
