    Now I know.
Since in that IRC conversation ceilometer's notification consumer was mentioned: there was some prototype work done on this (publishing messages to Zaqar off the notification bus to Zaqar) by Lei Zhang in the searchlight codebase - https://review.openstack.org/#/c/271958/. It would be reasonably straightforward to add a service to Zaqar to consume messages off the bus, and I would imagine that it's going to be easier in terms of getting things done to take the notifications (which are a well established format and mechanism) and the transformation to publish them in Zaqar than add a new component to all the individual services.
