You're right. It's been a while since I've messed with mogilefs. :)

I'm not sure how that maps then into a domain or what; I was simply
thinking of allowing mogilefs itself to do the replication for you.

This is true. Which is why if mogilefs will do it for you, I say let
it do it. Just get it safely into the system once. :)
