For example if I have a number of separate Nova instances I'd like to not have to manage the quota settings for a user separately in each one. >> Also, since quota clearly isn't an auth-n thing, is keystone way more auth-z >> than I realized? >RBAC and other functionality planned for Keystone is all about auth-z. >But, that said, I would not be opposed to having the quota/limits stuff >outside of Keystone.

I agree it doesn't have to Keystone - what I meant was that it should be possible to have a system outside of Nova manage these per-user settings, given that with Keystone users/projects are in effect foreign keys to entities who's life cycle is manages elsewhere.
