[Rdo-list] OpenStack Juno: best way to implement quotas?

My colleagues and I are looking at using OpenStack Juno internally using in various install methods (pre-packaged enterprise offering, manual via packages, etc. I picked RDO. I am responsible for evaluating quota usage. We'll have different development teams using our environment in one network. Each development team may have their own project where quotas can be adjusted when necessary. However, each project/tenant gets its own network. I wish I could associate multiple projects with one network. I was hoping to use projects in managing/implementing quotas (instances, cores, ram, storage, etc.) for the dev teams, but maybe I am approaching incorrectly. Any suggestions? Thanks. Steve
