Speaking as someone who's done a bunch of network programming in a
different environment (OS/X + Cocoa), I'm gonna pipe up @ this point
and say one of the things I really liked as a complete newbie to
Twisted was the Factory/Protocol/Transport separation (including the
names of the classes). Maybe that's because I started with the Finger
examples, which made things pretty clear IMHO.
