Proposal: Push and pull to P2P networks e.g ipfs, torrent, freenet, etc.

[LoveIsGrief]

I'm somewhat of a newcomer to docker, so if this is already done, feasible, or the wrong place to propose this, do point me in the right direction (website, codebase, file, etc.)

The following idea primarily comes from apt-transport-ipfs, apt-transport-tor, git-annex and simply git itself with special remotes, which allow retrieving data from sources using different protocols.

Introducing the possibility to push and pull from different protocols, would open up a world of possibilities and possibly increase download + upload speeds and reliability. If dockerhub or any other registry were to go down or go under heavy load, I imagine things wouldn't be pretty.

There has been an earlier proposal on this; #247, but probably better discussed in the containerd project (https://github.com/containerd/containerd, which (in future) will be used to handle push/pull of images.

And maybe in the OCI distribution spec repo (not created yet though)
