Thanks a lot. It definitely helped me. I knew how to set up a producer, I
just didn't know that my class was automatically going to be registered as a
consumer for transport. And I didn't know that i could call
transport.registerProducer(self.transport)! Unfortunately twisted is as
powerful as poorly documented sometimes.
