I totally agree that mirroring of official images should be easier, and right now it's an obstacle to easier production deployment. This is why it's important to have cryptographically signed, self-describing images. Then it becomes irrelevant where you download them from, and anyone could host a public or private mirror. I am 100% in favor of it and we are upgrading the registry system to allow it. Happy to chat more on #docker-dev.
