That sound very similar to the setup of the Coda webserver, which is
serving everything out of Coda. The `problem' I have noticed is that the
cache is gaining approximately 2MB every night. This seems to be related
to the the glimpseindex runs. I have not yet really looked into it, but
it might be related to unlinking (temporary) files that are still open.

have not been able to solve the replication issues themselves.
