[JDEV] Scalability Question

[Appleweed]

Hi... I understand the Jabber servers' ability to scale in terms of a large 
distributed network much like the way e-mail works. I also understand that 
each Jabber server has its own URI or domain-like address (ex: jabber.org). 
I'm curious how one would scale Jabber servers within a given domain. 
Specifically, can you have more than one server within a given domain to 
load-balance a large number of users? Or must each Jabber server have its 
own unique domain?

Thanks!
