After that , the Cinder team implemented nested quota in Cinder and at the same time, there was a plan to implement a quota library called  Delimiter.

But the main point is that we need to take a concrete decision in the approach that needs to be adopted, to make the things move forward.So IMHO it would be nice to have a discussion on hierarchical quotas at the PTG.

Thanks for the details.

I've posted hierarchical quotas as a discussion item in the Arch WG 
session at the PTG:
