[Twisted-Python] Flow-control for Pipes / Unix Domains Sockets?

[David Stainton]

Hi,

I don't know the answer to your question...
I've been thinking about flow control lately.

I recently wrote a little working prototype VPN in Twisted using
IPushProducer and IConsumer interfaces
but I have not yet implemented flow control :

Here we can see how I proxy between TUN and UDP using producers and consumers:

Perhaps later on I could add flow control... by having the consumers
pause the producers when need be.
For now I just churn packets as fast as possible.
