Ahem, some of us run Murderous Replicas all day long and it works well 
enough...  Doesn't it? ;-)

I can write this up, I just wasn't sure if it was still needed.  I put a 
big ol' Note: in the replication page saying:


    Within a Cyrus /Murder/
    environment, replicas must *not* be configured to invoke
    on startup (pushing the local mailbox list to the *Mupdate Master*).
    This may only be done on the Master instance.

That's the only real gotcha I know of, but, having said that, I did 
write up a brief set of instructions about this very topic not that long 
ago (IIRC) for user mailing list.  I figured I could start with that.
