Yes - that point of overlap is what the user cares about, I think.

I think that's exactly right. The messaging for Murano may end up as:
"if you're managing hybrid infrastructure (bare metal, containers, VM
instances) then you can use the same tool across all of them, using
OpenStack, with Murano as your application definition tool".

That seems like a powerful message if we see containers as an additional
instance type for OpenStack, whereas the "pure container" method of
CoreOS & Atomic Platform may make more sense if it's entirely green
field. I'm not sure which of those is true, but if I'm moving
infrastructure to OpenStack and I have the opportunity to embrace Docker
without changing my management tooling, I think I'd like that option.

Yes, I think that would be awesome.

Thanks,
Dave.
