Mission question for FunCom

I notice that there are two different styles of building type missions? There are the normal ones that usually open into some sort of great room (after the entrance room) and then there are the ones that I have only noticed in pleasant meadows that usually open into a single cell 4 door room (again, after the entrance room). Of course, there are also the caves, but that makes three different style.

I am interested in the network architecture behind this. Are there several different machines that generate missions and they each have different room templates? How many CPUs are there in an entire diminsion? Is there a seperate machine for moving between zones. Is there one machine per zone?

I'm sure you are aware that many of your players are in the IS industries and you must realize how curious we are. WIthout giving any real clues to network topology that might encourage intrusion, can you give us an over view of how the game system works?
