Archipel is a solution to manage and supervise virtual machines. No matter if you have a few locally on your computer or thousands through data centers, Archipel is a central solution to manage them all. You can use all libvirt-supported virtualization engines like KVM, Xen, OpenVZ, or VMWare. You can perform all basic virtualization commands and many other things like live migration, VMCasts, packages, etc. Archipel uses XMPP for all communication. There is no Web service or custom protocol. You just need at least one XMPP server, like eJabberd, to start playing with it. This allows Archipel to work completely in real time. You never have to refresh the user interface. You'll be notified as soon as something happens. You can even use your favorite chat clients to command your infrastructure. You can open a chat conversation with your virtual machine and say things like "How are you today?" or "Hey, please reboot."
JSONBOT is a remote event-driven framework for building bots that talk JSON to each other over XMPP. This distribution provides bots built on the JSONBOT framework for console, IRC, XMPP for the shell and WWW, and XMPP for the Google App Engine. A plugin infrastructure can be used to write your own functionality.
GOZERBOT is a channel bot that aids conversation in IRC channels and Jabber conference rooms. It's mainly used to serve RSS feeds and to have custom commands made for the channel. More then just a channel bot, GOZERBOT aims to provide a platform for the user to program his own bot and make it into something useful. This is done with a plugin structure that makes it easy to program your own. There are over 100 plugins already written and ready for use.
Saros is a Eclipse plugin for collaborative text editing that in particular targets distributed pair programming (also called remote pair programming), but can support arbitrarily many participants at once. All members of a session have an identical copy of an Eclipse project and Saros keeps these copies in sync as editing progresses.
Salut à Toi (or SàT: "Hi to You") is an XMPP/Jabber client with multi-frontends. You can use it on a desktop (Wix), with a console interface (Primitivus), as a command-line tool (jp), or on the Web (Libervia). A plugin architecture is used to make it modular. With SàT, you can perform all the expected XMPP functions (instant messaging, multi-user chat, file transfert, etc.), but you can also use your email client (MUA) to read and send your XMPP messages, play games, do microblogging, pipe Unix command results, make scripts, etc.
