Not quite true. The previous solution I discussed with MirrorMode and consumers using the
chaining overlay allows any of your clients to write to a consumer/slave from their point of
view. Behind the scenes the slaves are forwarding writes back to you active MirrorMode node in 
the MirrorMode pair.

So the benefits of this versus global multi-master:

1. All clients can write to their local consumer/s.
2. You only need to allow write access from known slaves/consumers/networks not any old client.
3. A write only need to propogate from a client to consumer to MirrorMode node, not every other Master.

There are many more pros and cons so feel free to ask more questions.
