If you're willing to describe your setup further, i'd love to hear about 
it.  I'm currently using client-side replication, and for the reasons of 
scalability you described, i'd like to move to a server-side replication 
setup.

In particular, i'm interested in how you handle the connectivity between 
the clients and the servers vis-à-vis load balancing (if any) and 
availability.  For example, in your configuration, how does a given 
client « know » which server to speak to, and what happens that server 
becomes inaccessible ?

I realise that this may not be necessarily be appropriate discussion for 
the devel mailing list, but iirc, you're not on the user list, hence the 
reply here.
