I would say not at an interval but as soon as there is an action 
performed on one mailbox, the other one would be pushed to do something. 
I believe that is called rolling replication.

I would not be really happy with a interval synchronisation. It would 
make it harder to use both platforms at the same time, and that is what 
I want as well. So there is a little-bit of load-balancing involved, but 
more and more _availability_.

Being able to use both platforms at the same time maybe implies that 
there is either no master/slave role or that this is auto-elected 
between the two and that this role is floating...
