Yay! I've had this pain for years now, I'm glad someone is finally addressing it. You need a lot more features (the most important being a decent IDE or editor integration with either emacs or something) before I'll use it, but, I'll definitely keep an eye on the project.
How is it different from <a href="http://vagrantup.com/" rel="nofollow">http://vagrantup.com/</a> -- Seems to have more features/support for chef/puppet?
