This is crazy talk of course, but I wonder if there'd be some way to use rsync or git to support distributed development of images the way git does with code?
I mean, it'd be neat to be able to do a "pull" of diffs from one image into another related image. Merge branches and so on. I don't know, possibly this would be just too unreliable, but I would have previously thought that what docker is doing right now would be too unreliable for production use, and lo and behold we have it and it's awesome.
There has been discussion of taking the git analogy further. We actually experimented with a lot of that early on (https://github.com/dotcloud/cloudlets) and I can tell you it's definitely possible to take the scm analogy too far :)
I do think we can still borrow a few interesting things from git. Including, potentially, their packfile format and cryptographic signatures of each diff. We'll see!
