Yes, that one. The pub/sub node is an intermediary, because it both sends and receives messages. But it's also the final-destination/service-provider. There are different kinds of intermediaries; some will be final destinations (gateways), and others will be routed-to (forward proxies ala WS-Routing) or routed-from (reverse proxies, ala WS-Referral). > Or is there no single answer to these questions, and it > all depends on the logical view that I want to apply to the scenario? There's definitely more than one way to design and/or execute a route of nodes to achieve some goal. But in each case, I believe all the roles should be apparent.
