Hey Stackers, I don't have the bandwidth to get this blueprint done, but if someone is interested in completing it, I would be inclined to support a freeze exception to get it into Essex since it would not be changing any interfaces or implementation -- just adding new event notifications to the outbound event pipeline... https://blueprints.launchpad.net/glance/+spec/glance-usage-notifications Assign yourself if you're interested! Cheers, -jay
