Yes, you could make your own custom OCF script to manage WANProxy, or you could
potentially have pacemaker start WANProxy using whatever init script is shipped
with the daemon as well.

yes, This sounds like basic resource failover, which is the primary reason
people use Pacemaker.

Pacemaker simply executes resource-agent scripts and is not concerned with what
those scripts do. If you want to modify configuration files for some reason,
build that logic into your custom OCF scripts and pacemaker will execute.
