Just name a specific example you'd like to see and I'll try to write something up. I don't want to pick something, write it up, and then discover that it doesn't cover what you wanted to learn. :) Jean-Paul

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? -a. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
