I've been waiting for someone to build something that would let me ditch Heroku and handle deployments and on my own infrastructure! This seems very promising
In the repo (github.com/sendhub/shipbuilder) I see that it is written in go-lang -- which is quickly becoming my favorite programming language.
It also uses HAProxy, which I've used many times in the past and it is easily the most powerful software load-balancer in existence.
What a potent combination of technology...will definitely be keeping an eye or two on this!
