Took a quick look. Introduction Billy the Kid is a Python Extension Module providing you with all kinds of more or less usefull stuff at the raw packet level. It allows you to create raw UDP/TCP/ICMP packets and it also includes a nice interface to libpcap. </quote> The author is 18 years old. Conrad, If you understand what this (snotty kid ;) ) just said - you are way ahead of me. So I am certainly not the right guy to be advising you on networking stuff. But I do understand that this is an extension module for Python, written in C. Not in Python. So please don't be intimidated by what you are seeing. C is not for me. But Lee's working demo of pygame in multi-player mode using Twisted - part of pygear - is where I intend to start - when I get around to tackling networking with Python. (And Lee thinks he's writing for kids). So the advise I gave you, is the advise I am giving myself. Lee seems to be looking for feedback. Might be more meaningful from you, then from someone like me. Have you taken a look? Does it seem to suit your needs, as a way to get started in writing working code. I sometimes think about learning how the pieces move, but then learning how to *play chess*. You want to start playing some chess, so to speak. I think Lee's book understands that. If indeed you are already beyond what Lee is teaching you might dig into the Twisted demos directly, perhaps. http://twistedmatrix.com/ Twisted looks *extremely* well documented Art
