We already run a sync_server on our masters as well because we use it for user moves:

As do we. In fact when I first showed the replication system to Rob Siemborski (few a years back now), he was thinking about using replication to replace XFER in a murder environment.

I have a special "-y" flag to sync_client which disables fsync() on the replica for fast seeding of replicas. We also use replication to dump data from the live systems to a tape spooling array each night. Replication is transaction safe rsync for Cyrus, tailored around the cyrus.index files.

More later.
