vmodemd is a telnet server designed to run old DOS BBS systems and door games. It listens for incoming TCP connections on a defined port, does a minimal telnet handshake if needed, and then starts to proxy all data to a PTY which is bound to a dosemu virtual serial port. vmodemd supports any number of virtual modems, can display customized banners if all modems are busy, can terminate a serial app when a telnet connection is unexpectedly dropped, and run custom scripts before passing control to dosemu, allowing you to pass relevant data like incoming IP address to the DOS app.

Sukiyaki was born out of what the author sees as a much needed improvement to current imageboard/BBS software. They're flaky, often have security flaws that users take advantage of, and worst of all, they have the same UI from the mid-nineties. It's time for an update! Sukiyaki visually organizes replies in threads so that it is clear who the reply is sent to. It is written using Django with its wonderful ORM, which helps reduce security vulnerabilities. It has been tested in production and is stable. It also includes a unique system for user-ranking of posts. Planned features include RSS updates for individual boards and threads, and there is a faster backend (Django-Treebeard).
Amethyst started as a port of Infobot to POE, continuing as a generic bot core with the ability to handle multiple connections using different protocols (not necessarily IRC) and soft route the incoming messages through a number of processing centres. One of these processing centres contains much of the original Infobot core.
