That's about the idea I had about it, but I couldn't quite grasp it.
I'm curious though: wouldn't it be much more pythonic to allow users to register a generator with the transport? A generator usually does exactly what is expected from a pull-producer.
Do you/does anyone know if that's foreseen somewhere in Twisted, either now or in a later version?
