In a large scale server - client game, can anyone suggest methods other than having specific loadable areas (ie. zones you move from one, wait while the next opens, move through that, etc) for running a game world across several different servers? Thanks!

I have been thinking about this a lot recently. You would probably need some dynamic load-balancing mechanism that evenly distributes the work that needs to be done to the different servers. Most of the design work on such a system would probably be about minimizing the amount data that needs to be exchanged between the servers. One really needs to take this into consideration when designing the memory structures that hold the data in the game (the maps, players etc.).
