Hi Michael,

i have put your drawing online so others can view
it as well (it got bounced by the mailing list):

http://www.xmlblaster.org/xb-cluster.png

Probably the 'crossing arrows' between

  frodo - saroman

and

  bilbo - sauron

is too complicated. In such a case the messages need to convey
the information that they have reached the other master
already with the direct connection frodo->sauron and
bilbo->saroman and don't need to be mirrored anymore.
And further, it is questionable if bilbo or frodo should
have knowledge about the backend master cluster setup.
This cluster setup could change to 3 or more mirrored master nodes
or sauron could go for maintenance and another mirror
node 'gandalf' pops up.

Conceptually it could be more wise to only mirror on
master level sauron<-->saroman, what do you think?

Marcel
