Yeah, that's pretty ancient.

So I'll be talking about this in a couple of weeks if you want to make
your way over to The Hague :)

The short version: replication in 2.4/2.5 is very stable. We're using it
at FastMail and have been in production for about 5 years now.

It doesn't integrate very well with murder yet though. We don't use
murder at FastMail.

My plan in the short to medium term is to merge replication/murder into
a general better HA system. I'd be very interested in having test cases
:) (as well as FastMail moving to it)
