Open Stack

So I have substantial concerns about hierarchy based designs and data
mass - the interconnect between leaves in the hierarchy are often
going to be fairly thin, particularly if they are geographically
distributed, so the semantics of what is allowed to access what data
resource (glance, swift, cinder, manilla) need some very careful
thought, and the way those restrictions are portrayed to the user to
avoid confusion needs even more thought.
