Thoughts of a Docker registry type service?  Should be fairly simple, just another Flask server talking with a Docker daemon that runs the service (https://hub.docker.com/_/registry/).

Would be a nice place to host images: registry.sr.ht/~username/git:latest

I'm not sure that this is in the cards right now. However, it'd be a
pretty cool third-party integration once I get the OAuth docs written
and the API improved.
