Thanks of the update on this work.
I see that your proof of concept shows how this can work as a tool
outside of Nova:
So, my biggest question is whether or not it makes sense for this to be
a Nova feature or not. If something can be implemented as a consumer of
Nova, my default answer is that it should stay outside of nova until I
am convinced otherwise. :-)
It sounds like this is mostly an extension to nova that implements a
series of operations that can be done just as well outside of Nova. Are
there enhancements you are making or scenarios that won't work at all
unless it lives inside of Nova?
If it doesn't end up on the server side, it could potentially be
implemented as an extension to novaclient.
