Fedora directory users - Apr 2008 - 2xMulti-Masters Replicating to 2xDedicated Consumers

Fedora Directory List,
 
I have two Multi-Master replicated servers at our main datacentre
replicating between each other. 
 
I also have two Dedicated Consumers at our DR site receiving updates.
Both Dedicated Consumers receive updates from both Multi-Masters (this
is incase one of the Multi-Masters dies for whatever reason).
 
It works - and seems to work well. I imagine in a true DR situation I
would change both Dedicated Consumers to be Multi-Masters and set them
up to replicate between themselves.
 
My question is - am I following conventional wisdom and best practice by
forming this setup arrangement?
 
Thanks
 
Joel
