Currently the Open Container Initiative doesn't specify a distribution protocol or system, and the current "standard" format is the Docker registry protocol. Aside from technical reservations with Docker registry, it is also not an OCI-compliant system and will require a lot of work to integrate it into all of the openSUSE/SUSE tooling.

So, a very insane idea I came up with is to convert OCI images to RPMs and then distribute them as simple RPMs. The idea would be to use capabilities (Provides: oci(...)) to implement the different names of images and then also the dependency graph of blobs (which would naturally be de-duplicated).
