How are you proposing that this integrate with Swift's account and container quotas (especially since there may be hundreds of thousands of accounts and millions (billions?) of containers in a single Swift cluster)? A centralized lookup for quotas doesn't really seem to be a scalable solution.

Centralized quota storage in Keystone is an anticipated feature, but there are concerns about adding quota enforcement logic for every service to Keystone.
