Maybe you should more about the amount of users, and how they are
spread.  We can give much better advice if we know what you are
trying to do.

A single server can easely support a few thousand clients.

You can use special servers who's only function is to hub, they
have little or no clients, only servers.  They would route the
message from one server to the other.  You want to group servers
based on the netwerk.

The clients aren't supposed to connect to the hub.  There is no
way for the server to pass the connection to an other.  You can
setup an round robin for the client servers.

What kind of numbers are you intrested in?  How many clients a
server can support, how many servers it can link?

It really depends on your hardware and OS.
