We use CARP on FreeBSD for active/active clustering across 4 nodes. We
use DNS for round-robin load balancing and Carp for keeping the 4
virtual ip's up. The varnish instances don't need to know about each
other or the fact that they're part of a cluster.

About the configuration: on each node we have a script we run manually
to refresh it's configs and restart services.
