  | The mep was introduced to control this, providing explicit instruction to the pipeline stating how it should handle any responses.

  | This is nothing to do with a client contract, which we don't really have, and cannot be used to determine client behaviour.

  | Look through the async continuation stuff for more examples of how easy it is to use OneWay services to implement request/response behaviour.

Sorry... I sent the last one before getting to this.

Sorry again, but this all seems a bit confusing to me in the context of the Http Gateway use cases, that I have in my head.  Perhaps I'm a total idiot, but I just don't follow this.  Am I alone here?
