Yeah, I'd love to see something like that. I would really like to see
more effort in this area. I honestly haven't been thinking about it
much in a while personally, because the rest of the "make it work" gaps
have still been a work in progress.
There's a bit of a bigger set of questions here, too ...
Should nova-network *ever* go away? Or will there always just be a
choice between the basic/legacy nova-network option, and the new fancy
SDN-enabling Neutron option? Is the Neutron team's time better spent on
OpenDaylight integration than the existing open source plugins?
Depending on the answers to those questions, the non-visible no-downtime
migration path may be a less important issue.
