Now that is some cool stuff. I started my server/listener with the Cookbook since it has basic TCP Servers and Clients in there. As I started looking at my requirements, such as IPv6, looping and future functionality I thought to keep it simple and understand it first. That's worked out well, and it looks like that Network Programming With Perl book will help me out in the future; I'll check on that one. I'll take a look at Net::Server and start playing around with it, and IPv6, and see what I can get to next.

Thanks!
