We now have two competing open source projects
Doug, one way to test that notion is to have two open source projects competing with each other, which is what we have now. If Docker is going in its own commercial direction, as opposed to what developers want, then its popularity will fall off. No sign of that yet. If it's doing the right thing for developers, it will push hard into new "platform areas" and get more firmly established. So far it's actions indicate speed of development trumps community consensus. Meanwhile, we can gauge the degree of support for Rocket and watch who uses it. If a broad community forms behind it, and there's a good possibility one will, that will also tell us that Docker doesn't fit all needs and uses.
