I think many organisations will have them be the same, and we should
indeed optimise for that.
Several organisations have had discussions with Devananda and myself
(sometimes even at the same time! :)) about running multi-tenant
baremetal clouds. For instance, datacentre operators may want to run
infrastructure and let their clients run public clouds. There's
obviously a bunch of work needed to have baremetal multi-tenancy be a
sane thing, but I think TripleO needs to fit for these cases as well -
eventually. All we need to do about this today is to be clear that
folk deploying clouds - overcloud operators - should only need regular
tenant privs on the undercloud, vs being undercloud admins.

Radical idea : we could ask (e.g. on -operators) for a few potential
users who'd be willing to let us interview them.
