Hi Rob,
I didn't know you could do reliable multicasting, do you have any
refernce to an RFC or other document ?

Anyway the main problem would be changing quite drastically the
replication engine. It would also have impact over the replication
topology. Something we should think about, but it's going to be a very
long term thing. The amount of changes required to do something like
that looks quite big.

Simo.
