I'm glad to see work in the area of making linux containers more accessible. I recently stumbled upon openruko[1], an open source Heroku clone, and from there discovered linux containers and lxc[2]. It takes a bit of configuration to set up useful containers, though. I think the ideas behind Heroku and The Twelve-Factor App[3] are good, and containers are an important building block. I'm excited to see (and I'd like to see more) tools like Docker that aid in robust and streamlined container-based deployments in-house.
