Sounds too structured for my taste. One of the things I enjoy about LFS is that I can hop on any server and find someone from virtually every country in the world.
I am assuming a setup like that would give the option to change the nation of the servers, but to me that just puts a bad taste in my mouth. I like diversity, and segregation is not a way I would like to go, which is what a system like that does. It's saying you are from here, so you use this server, and your from here, so use this server.
Sure you can still join other servers, but from the get go a driver is channeled into national servers like herding cattle... and lets face it everyone is lazy and most people will probably just stick to their national servers because they don't want to spend the effort to find the more international servers.
