Hey, me too!  I wonder if anyone else out there is doing this -- it seems
like a natural combination of technologies.

Everyone I've spoken to has recommended not using threads with Twisted.

I hadn't seen that discussion thread before, and I'm not that familiar with

What I'm currently doing is this:

def renderFrame():

renderTask = task.LoopingCall(renderFrame)
renderTask.start(0.01, False)

I do my keyboard and mouse capture in a frame listener which I register with

It works, but I've only done a little bit of network activity (e.g. an IRC

If any Twisted experts would care to comment on the above code, I'd
appreciate it.

I'm also wondering what would be the advantages of using a coiterator...?
