Not in Varnish itself, no. You need some sort of clustering framework
around Varnish. Also, Varnish can act like a load balancer for it's
backend web servers, creating a logical cluster of servers behind it.

The Varnish Administration Console (the VAC - we can't create anything
without giving it a three letter acronym :-) is focused mostly on
administration and monitoring of Varnish, not so much doing the actual
clustering. Features that will enhance the clustering capabilities
will be built into the VAC next year.

And yes. We have decided to keep that application proprietary - so you
would need a service agreement. Get in touch with me if you are
interested in giving it a try.
