Basically App Containers is about laying down the gauntlet for Docker because the changes they are asking for are/were unlikely to be accepted without backing them up with the pressure of facing a competing project if they're not.

The federated nature of image identity that CoreOS is pushing for is a direct challenge to the special status that Docker has given index.docker.io, and that they have been strongly resisting attempts to change.

I don't care much if Rocket or Docker "wins", but I really hope the App Container federated approach does.

Right, in which case this should be the messaging instead of "Look guys docker can run ACI images". Why waste effort on interoperability if the end game is federated image identities? Pour all engineering resources into making that happen instead of silly patches for interop since that can always happen later.
