How about this scenario:

I make an HTTP request and expect to receive an XML
document back. The XML document is a container for
discreet items.

It might look something like this: 

<items>
  <item>
    <content>foo</content>
  </item>
  <item>
    <content>bar</content>
  </item>
</items>

I don't know how big this document will be or how long
it will take to retrieve so I would like to present
myself as a producer of individual item elements and
let clients consume them as they become available.
Does this fit the twisted Producer/Consumer paradigm?
