Hey Solomon, thank you for sharing your thoughts, love your work!

1. Yeah agreed, it's a bit of a mess that we have at least three different file system layouts for images and two image stores in the engine. I believe it's still not too late for Docker to achieve what you described without breaking the current model. Not sure if they care though, they're having hard times

2. Hm, push-to-cluster deployment sounds clever. I'm definitely thinking about a distributed image store, e.g. embedding unregistry in every node so that they can pull and share images between each other. But triggering a deployment on push is something I need to think through. Thanks for the idea!
