In AMQP 1.0, what we have as an exchange and a queue are being placed into a single concept. This makes this like JMS topics a bit easier to deal with in the broker. In AMQP 1.0 you can think of an existing exchange as a AMQP 1.0 queue with 0 length and a queue in AMQP 1.0 as a 0-10 queue with a server side selector attched. So the mapping to 1.0 from a model stand point will be quite natural. One of the features that have today in the C++ broker, the IVE (Initial Value Exchange) which is basically a AMQP 1.0 queue construct with a queue depth policy of 1. hope that helps Carl.
