#3 involves changes to the update code to have cyrus take special actions
with soem types of updates. there would need to be changes in the same
area for #5, but they would be different.

Mike, one of the problems with this is that different databases have
different interfaces and capabilities.
if you design it to work on Oracle then if you try to make it work on
MySQL there are going
to be identified in the code and hooks put in place in
the code at those locations. the details of the hooks will differ slightly

for performance we already have murder, what we currently lack is
redundancy. once we have

would be so far ahead of where we are now that the need to reconfigure
murder for a failover is realitivly trivial by comparison.

also take a look at the heartbeat package at linux-ha.org This works on
linux, *BSD, and solaris (there were people working on a AIX port, but

on it, but don't stop maintaining the current version, the apache
