Ok.... but that begs a few follow-up questions:

1. Has anybody tried it? (And documented it?)

2. It seems like there's a point at which explicit 1-1 replication 
starts to be an administrative nightmare.  Some kind of 
publish-subscribe or multi-cast update model seems needed.


In theory, there is no difference between theory and practice.
In practice, there is.   .... Yogi Berra
