Of course, if I could go back and do it all over again, I would have generalized this code and made it into a CPAN module so that everyone could've used it. Fortunately, it looks like POE::Component::Server::IRC filled that void.
Out of sheer stubbornness, I've continued to maintain the original hyperlinks over the years, and I just recently put up a somewhat abbreviated repository of the code at
https://github.com/v64/vircd.
Let bygones be bygones?
