That's the root of this thread. Marconi is not really designed to cover
Robert's use case, which would be to be consumed internally by OpenStack
as a message queue.

I classify Marconi as an "application building block" (IaaS+), a
convenient, SQS-like way for cloud application builders to pass data
around without having to spin up their own message queue in a VM. I
think that's a relevant use case, as long as performance is not an order
of magnitude worse than the "spin up your own in a VM" alternative.
Personally I don't consider "serving the internal needs of OpenStack" as
a feature blocker. It would be nice if it could, but the IaaS+ use case
is IMHO compelling enough.
