The Tcl IRCd is a small IRC server written in Tcl. It is very simple to modify. It is not a full implementation of the IRC protocol, but it's enough to create channels, talk in public or private, change topic, nick, and other basic operations. No configuration is required. The server is designed so that it can reload an updated version of itself at runtime without closing client connections.

It includes plain text chat and video chat options, and is scalable enough to fit the needs of small business and large enterprises. A free 10-user edition is available. It's based on a Java server and a Flash client, but also has various alternative clients based on technologies such as HTML/AJAX, so it can run on many platforms, including iPhone and iPad. It features avatars, smilies, Flash emotions, voice messages, entering multiple rooms, dynamic skins, loading external avatars and profiles, and a media player. The HTML 5 client significantly improves the chat performance in terms of loading speed, video layout, and user interface.

autodl-irssi is an advanced and easy to use torrent file downloader plugin for Irssi. The optional ruTorrent plugin (GUI) makes it even easier to use. The installer will set everything up. It works by connecting to your torrent tracker's IRC announce channel. You tell it exactly which IRC servers and channels to connect to and it does the rest. When a new torrent is announced, and matches one of the user filters, it's immediately downloaded. There's no delay like RSS, which polls once every 5-15 minutes. Once downloaded, the torrent file can be saved to a torrent client watch directory, sent to rtorrent, or uploaded to an FTP server. It supports more than 70 private trackers, and it's very easy to add your own if you know some basic XML and regular expressions. The filters are easy to set up, but also advanced. Some of the filters are release name, TV show name, torrent size, resolution, encoder, source, year, format, bitrate, medium, category, and many more. To prevent you from accidentally downloading too many files at once, you can also tell it to only allow X number of downloads per day, week, or month.
