I'm inclined to agree; if you're going to have some mechanism set up (as 
you must for mirrormode) to ensure that writes only go to one server, I 
believe it would make the most sense to use that same mechanism for 
replica determination. If your writes are (mis)directed, it'd make sense 
for your replicas to be similarly (mis)directed.
