All, From an upper level management stack perspective, has anyone else seen the need for AMQP based notifications from Keystone identity and/or heard of any activity in this space? For example, similar to nova's notification system (https://wiki.openstack.org/wiki/SystemUsageData based on https://wiki.openstack.org/wiki/NotificationSystem), but for events such as user/role/project/domain CRUD? I've come across this requirement a few times now, but have not turned up any hits via google-foo. Thanks
