Look a lot like containers. But docker is a bit more than that, the first that jumped to my attention is what is related to filesystem (layered images, repositories, CoW image+running container fs, volumes) seem to be missing. It runs everything in the normal filesystem by default? The ecosystem build around it (compose, kubernetes, weave, machine, swarm, etc) will be missing too. Its desktop app focus made me remember of http://subuser.org/ http://subuser.org/ that is docker based, but maybe it have less requirements. But is another voice in the container space, and could be more fitting than other alternatives for some use cases.
