I asked because I was wondering if there is a way in rabbit how to
emulate read-only queue browsing, as supported by Qpid. (I think they
support it because they are so JMS-like.)

I guess currently this can only be done in rabbit using the management
plugin? And should not be used for regular processing, but only for
ad-hoc monitoring?

I understand queue browsing is not in AMQP standard, but a Qpid
extension, correct?

What about the message ordering on reject - I assume the specs does not
say where should a requeued message appear on the queue?
