colloquy is an Internet talker server. It lets people all around the world talk to each other in real time. It is inspired by The Nilex Talker and Egham Hills, a popular "technical" talker in the UK. It is explicitly designed not to have "socials" and "custom rooms" and other bloat that just gets in the way of idle chat like many other talker servers.
DutchPIPE allows Web developers to make virtual multi-user "avatar" environments. Each Web page becomes an abstracted environment or location where visitors and other items on the page are visualized. This status is retained as visitors move around. A lot of real-time interaction is possible, resulting in persistent interactive page environments. DutchPIPE uses AJAX and the DOM for the browser, and it works without Java, Flash, plugins, or firewall adjustments.
Fljud (the Flexible LDAP Jabber User Directory) is a JUD that uses an LDAP directory for user information. You may find it to be very useful if you already have a Jabber server using LDAP for account authentication and vcards. It can replace your existing JUD, or can be quickly adapted to present and edit other information from your LDAP directory using Jabber.
