This sounds a lot like what we talked about in the Midcycle when we discussed this topic. We’ll take a good look at this. I’m planning for this topic to be at least one of our Design session topics, and would love to coordinate for OVS contributors and Neutron stakeholders to join us. Thanks for sharing this proposal with us!

Keep in mind that my characterization of “Overlay Networking” does not necessarily mean double encapsulation. It means having a reliable means for containers to communicate across hosts using an IP address scheme that is user-supplied.
