By mistake I replied to Gavin Henry and not the list, I am sorry for this.

If I understood it correctly, on N-way Multi-Master replication any member can
accept write operations while on MirrorMode only must|should accept write
I had a MirrorMode configured and I was able to send writes on
both servers and each server was replicating the changes without problems.
The test which I did was very simple, first add/remove an entry on the first
and then add/remove an entry on the second.
So, the above test made to wonder about the differences between MirrorMode and
what is the reason on a MirrorMode replication to force all write operations to
one of the members of the replication?
BTW, what about the syncpro overlay settings which are not part of the
MirrorMode configuration example?
