This would fall victim to the phenomenon of 'flash crowds' or 'stampeding
herds' or whatever it should be called. With this type of static
distribution scheme, you can run into some trouble if a large number of
users (or objects, or whatever) decide to go visit some area on a single
server.

I tend to think about it roughly this way and with the use of events, but I
need to put a lot more thought into my current set of thoughts.

Why does AI get treated any different from any other client connected to the
game? (Making a lot of assumptions: clients aren't accessing world via flat
text that they just display, like telnet; that there are clients; etc).
