Awesome summary & more or less exactly what I think.

The goal is: allow someone using one OpenStack cloud to move *his* stuff
to another OpenStack cloud easily. Also allow someone to burst from a
private OpenStack cloud to a public OpenStack cloud easily on demand.
That could be achieved by interoperability, but the definition of
interoperability could also be too narrow to allow that.

Third option: standardise on interfaces and behaviour, and ignore
