Designed for the Bahamut, Hybrid, and ircu IRCds, bopm is a replacement for first generation proxy monitors (wgmon, tcm). It extends them by adding support for SOCKS4, SOCKS5, WinGate, HTTP proxies, insecure Cisco routers, HTTP POST proxies, simultaneous connections, and a more scalable model (written in C). BOPM also has support for a DNS blacklist, similar to MAPS RBL+ or Visi RSL.
CGI:IRC is a Perl/CGI program that allows you to use IRC from a Web browser without having to have access to an IRC port. It does not use Java, but it does need a browser capable of rendering frames. It can be used on a Web page to allow users to chat, or it can be used to access chat from behind a firewall.
