That reminds me of the early work on the internet arguing that the amount of global connectivity wouldn't scale due to power laws. In a way, they were assuming a system like these global world sims. The equivalent of static routing (players that want to play together enter same server) exists, but the "dynamic routing" field is mostly a game of selecting which illusion to present the player (sometimes, it's okay to just stick people on a different instance but make sure their friend group is preferentially on the same one, etc).
