No no, not really. Ceilometer consume one notification from the
notification AMQP bus, transforms it into several meters, then emits
these meters on the RPC again.
My idea is to provide a notifier driver (that could be used with or
without the RPC notifier driver) to emits directly the meters and avoid
one round-trip and useless AMQP load if someone doesn't care especially
about notifications being on the AMQP bus.
