Wosh! I never expected a detailed reply like this! Thanks!

The more I do my research.. The more it looks like a single server
approach is just out for an MMOG.

This is the idea that I keep thinking about..
The users client will connect to a login server the login server
just verifies the users account and assigned a session ID to this
users. This session ID is also put into a active session table in
the database linking session to this users profile.
There will be at least 3 login server to help support redundancy and
failover.
Each major land mass will be a "zone" in the game world and managed
by it own cluster of servers. This cluster of server will manage
the game logic, map data, presentation and other event local to this
zone only. Each zone will have its own independent database server.

I couldn't even begin to afford something like
this... Unfortunately, the server side is going to have to be x86
based. At least this version.

Wow, This is great! I'm going to have to get with my team.. and
work out a list like this and see what we can come up with!
Thanks alot again!!
