It's here: Docker 1.0

I've wanted to try it ever since pyTennessee, but it looked like it didn't make sense for spinning up a one-off hobby project. Without using it to grapple with the problems it is supposed to solve, I feel like I'd just be running through a tutorial which I could do just as easily when I actually need Docker.
Its basically a build script that is less than 100 lines, generally, so it is really easy to use.
Just add "FROM deis/python-runtime" to the top of your project and declare a CMD or an ENTRYPOINT in your Dockerfile and suddenly you have a python project installed and ready to go.
It doesn't mean modifying the Dockerfile.
One of the greatest things about Docker is it lets you consolidate your setup environments. You can great a handful of 2k scripts, store them in Dropbox, and then if you current development machine bites it, a simple "docker add <script>" gets you up and running exactly as before.
Docker lets you stop treating your personal machine as a server. And that's a beautiful thing.
It looks like a solution for https://github.com/dotcloud/docker/issues/1228 didn't make it into 1.0 after all.
