I've been running OpenVZ for years - It works very well. LXC is built into the kernel directly, rather than a patch, which is very nice. So far as I can see, Docker is just some nice wrapper scripts around LXC, nothing particularly revolutionary in and of itself.

Correct, docker is not an implementation of linux containers. The heavy lifting is done by lxc (and alternatives like openvz). What docker brings is a way for backend developers to package and distribute their app into portable, sandboxed containers (think "iphone apps for the server"). This is only possible now that linux has decent container support, because it means the vast majority of servers out there can potentially run a docker container unmodified.
