Resolution: Fixed
> QMFv2 - Allow endpoints to be directly addressed via a topic exchange

> Key: QPID-3032
> URL: https://issues.apache.org/jira/browse/QPID-3032
> Project: Qpid
> Issue Type: Improvement
> Components: Qpid Managment Framework
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Minor
> Fix For: 0.9

>
> QMF uses a number of messaging patterns, including direct to single
> destination and request-response using the reply-to header for the address of
> the response message. This enhancement allows direct addressing to be done
> using the topic exchange rather than the direct exchange. This has a number
> of advantages:
> 1) It allows a QMF domain to be configured using only one topic exchange,
> which is simpler than pairing a direct and a topic exchange.
> 2) It allows security policy to be applied (details below) because the
> topic-wildcard feature can be used in broker ACLs.
> 3) It allows for scaling into large networks of brokers where inter-broker
> links are summarized and direct topic routing keys are defined hierarchically
> based on topology.
> Details on security policy:
> With this enhancement, it is possible to write a very concise policy (using
> broker ACLs) that restricts user roles to be "QMF Agent Only", or "QMF
> Console Only", or any combination of these. Furthermore, since a QMF domain
> is tied to an exchange, these policies can be independently applied to
> different domains.
> Code changes needed:
> 1) QMFv2 implementation uses the topic exchange as the basis for direct
> addresses (agent direct, and console reply-to)
> 2) The legacy C++ agent (qpid::agent) must be able to send a message to any
> arbitrary reply-to.
> 3) The broker-agent must be able to send a message to any arbitrary reply-to.
> Note that the broker and C++ agents currently only use the "routing-key"
> portion of the reply-to. They hard-code the "exchange" portion as
> amq.direct. This is arguably a bug in its own right.
