I think in a M-M mode, updates from both dbs will be replicated to the other db.
In other words they will be eventually consistent.
In a M-S mode, even though Slaves can be updated by the app, its updates will
not be replicated back to the master. While updates from M->S will happen all
the time, updates from S will not go to M.
