No, I don't want a mirror.  I want it on multiple systems.  I want
replication (preferrably in "realtime" -- as the write goes to one
machine, it goes to all of them that are replicating.)  Just to explain
why so people have a better understanding.  I work for an ISP.  We are
growing like you wouldn't believe.  So what I want to implement is
something that will scale our servers well and give me the most uptime
possible.  I like NFS, but I don't want to rely on NFS.  It provides a
single point of failure.  I want to eliminate that if possible.  The best
way to do that is with replication.
