[Twisted-Python] Utility program to hex-dump network traffic

Dear Twisted Experts, About 2 years ago I needed a simple way to hexdump network traffic. I threw together a Twisted application, and have improved it little by little whenever I needed to. I didn't want to use an existing network sniffer tool. Instead, I borrowed the idea of a tunnel from ssh: Normally application A connects directly to application B; instead, A connects to the tunnel which connets to B. I posted the program to the ASPN site: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/502293 Though it works well for my purposes, I'm sure I've got some aspects wrong -- any/all comments/feedback/advice would be warmly appreciated :) Regards Andrew
