In the "replicated" mupdate_config, each backend (nothing to do with  
replication) is meant to serve data from a common mail spool, while  
maintaining a "replicated" copy of mailboxes.db.  The changes to  
implement this IMAP_ENUM_MUPDATE_CONFIG_REPLICATED are isolated to  
imap/mupdate-client.c, effectively to just remove references to the  
backend server.  So, this configuration would remove the various  
locking problems surrounding mailboxes.db, since each backend would  
be maintaining a separate copy.  Any concerns related to locking in  
the mail spool would still be relevant, tho that locking is typically  
less esoteric.  You'd need to have an mupdate master as well.
