Adding servers to multi-server setup

    Hi, I've had a multi-server setup for some time, and I've recently added a couple of nameservers to the setup which I had some issues with (entirely my own fault as I got them the wrong way round so db permissions were swapped, oops...)

    It's got me thinking, I want to add some redundancy to my server setup if possible, my setup is as so:
    VPS4 (webserver) ¬
    VPS5 (mail server)
    NS3 (name server)
    NS4 (name server)

    VPS4 is the master server, with the ispconfig interface...

    My hope is that it's possible to be able to add replication to VPS4 and VPS5, I know I can use unison for the files but in terms of the database, would this just be the same as explained in a cluster setup? Or because I've got a multi server setup, replication/cluster setups are incompatible?
