Duncan, Looks like we're in the same boat--this is my third day looking at Twisted. My approach is to skim the doc and read some code, sleep on it, then do it all again but a bit more carefully. And yes, my head hurts. ;-) But I have enjoyed reading the reactor code. My only question there is if anyone is considering using heapq instead of insort, as heapq is really the algorithm of choice for processing dynamicly changing lists in order. So while my head really hurts, at least I'm enjoying the code. And its a nice break from reading the docs, too.

Can anyone offer guidance or suggestions as to the approach? Right now, I am locked on the example here: http://twistedmatrix.com/documents/current/howto/application.html ... Yahoo!
