KDX is a powerful cross-platform BBS-style encrypted Internet communications system that provides messaging, news, file and folder transfer, voice chat (Internet Telephone), text chat, remote access, trackers, and more. It uses strong encryption to protect communications for security and privacy. It is useful for groups that need to collaborate on a project via the Internet. It is also very useful for remote administration of a computer. It uses a client/server architecture.
Volley is a modular client/server application for chat, file sharing, and so forth. It is similar to Hotline, except its modular design allows for the addition of more services than just the usual chat, files, and news; there could be multiplayer games, and online meeting tools such as virtual whiteboards.
BBSzilla is an extension for Mozilla-based browsers such as the Mozilla Application Suite and Firefox. It gives the browser the ability to connect to Bulletin Board Systems that utilize TCP/IP, such as Hotline servers. There is functionality for multi-user chat, single-user messaging, as well as server-side and P2P file sharing, threaded news, single-thread bulletins, and more.
panFora is a full featured, high performance Web-based collaboration tool for discussion forums and file sharing. Using standard web browsers and a multi-framed/windowed approach, it has a desktop application feel familiar to users of desktop email/newsgroup tools. A traditional single-frame web layout is also available as a user preference. Extensive admin features allow forums to be created, customized, colorized, reconfigured and maintained, completely from the web. Other unique features include hierarchical topic structure, announcements by groups, and full but safe HTML formatting support in message posts. A popular high performance open-source embedded database is built-in; no database installation is required by the user, making panFora installation fast and easy.
OPT (Outreach Project Tool) is a PHP general-purpose virtual commonplace for customers and developers to collaborate in developing projects. The system provides documents archive, e-mail archive, request tracker, task management, knowledge base, news administration, newsletter support, and a lot of other features (some project-based, some system-based).
This program hopes to become a viable MS Sharepoint clone. It is basically a Web interface to a document repository (Frontpage Web), but with many other features. It depends on Frontpage extensions for remote authoring; otherwise it is independent. It includes a forum, calendar, event tracking, announcements, tasks, file check in/check out, user management, email, and more.
Chindi is a file transfer server/client package written in Java with functionality similar to that of an FTP server. The goal is to create an old-school BBS-system combined with a FTP server. All transfers are encrypted using a fast stream cipher combined with RSA encryption for the transfer of the keys.
