I like the concept of quota. But I am thinking whether this should be a core part of CS or developed as a plugin. Cloud coins example given below may be a plugin, based on which decision to allow/disallow operation is made. Another plugin could be to allow/disallow operations based on VM count or say the current storage used in bytes. There should be flexibility to put in a condition of choice by the developer/user. If there are multiple such plugins, an option should be provided to decide the ordering of the plugins (similar to the various host investigators that are available).

I think the global limits and quota are quite different, Account/Global limits are per resource are to limit a user/account to run/deploy/use maximum amount of a resource, for example number of VMs a user can deploy. Quota is to block new demands from a user/account once they exhaust their quota/credit. For example, we can give some quota to a user which is giving them 1000 cloud coins (credit), each cloud resource such as ip address and VMs have a flat quota rate (for example, 10 points per IP); the user deploys bunch of VMs and consumes some public IPs etc, and finally the user exhausts the quota and the quota system blocks the user to demand any new resource.
