I think it might be a bit early to start a cross-project discussion on
this.
I'd suggest to first figure out what questions do we have, what would we
like to get from nova.
So I think it'd be more constructive if we first think on it within neutron
team.
I left some questions on the bug [1], please see comment #8

Thanks,
Oleg
