Cool thing is the speed and non-intrusive nature how it's accomplished. You have to do very little. Let us know if you would like to deploy it, we are here for you :)
Thanks for the compliment, sounds like you have a use case.
It would be cool if we can connect on our git repo (https://github.com/varnish/zipnish/issues) we would definitely like to see how we can integrate with kubernetes.
