Thanks for the SimSig comments
One real world model you could perhaps relate to is that of the flight sim world. A plethora of tools exist for MSFS, but the most powerful force is a group of users - pilots and air traffic control.
To combat the loneliness felt in multi-player simulations, these groups often have "meets" in the virtual sense - for example, they would pick a route such as Heathrow to Amsterdam and have continuous ATC throughout the route and numerous aircraft flying. Suddenly Heathrow comes to life with dozens of aircraft taxiing, taking off, landing, holding, etc.
To combat the "newbies", there are grades that must be achieved. For example, a newbie ATC wouldn't be allowed to take over Heathrow. He would need training on a smaller airport first, before moving up through the grades.
I tried to talk to Kuju about integrating SimSig into KRS but they weren't too interested. It remains to be seen how flexible and extendable it will be. But MSTS2 *might* have that kind of option, if it's modelled on MSFS-X.
Anyway, enough ramblings from me for now.
