How would changes from MASTER be replicated to MASTER MASTER?
The administrative people at the MASTER MASTER location would never see
changes made to a lowly MASTER.

You can daisy-chain replication: MASTER->SLAVE->SLAVE and all the
changes from the slaves should be referred back to the MASTER.  Changes
are usually pretty infrequent (passwords, etc..) and don't use much
bandwidth.

Or you could MULTIMASTER<->MULTIMASTER but you cannot chain replication
if you are using MULTIMASTER.
