Nope, I don't think this is it. The problem with lxc, jails, zones, is that of shipping the state of the containers. Docker solves this with the registry. I think that they would each be as successful (or more-so as the tech is more baked in) if they had a better developer story. Being able to docker pull/commit/push is what made docker so popular with developers. The "alternatives" all seem to lack this. I almost see it like I see dpkg vs apt-get. You can do what you need with a pile of deb files and dpkg -i, but why, when you can simply apt-get install? Same concept.
