    This issue is actually currently being worked on.  *CURRENTLY*, with the
1.0 release, the servers do not have out of the box capability to scale to
multiple servers, and hence, are limited to the maximum capability of a
single box.  As part of CVS currently, there is a mux module that allows
jservers to be multiplexed accross several machines, allowing a load
balancing situation to take place accross multiple machines.  The 'logic'
behind this is part of svc_farm.

    So basically, the current 1.0 release cannot scale well for a single
domain, but this issue is being actively resolved as part of the 'summer'
session.  See http://core.jabber.org/summer.html for a full list.  Your
question is specifically addressed in
