http://openaether.org/projects.htmlOpenAether is primarily a toolkit for XMPP/Jabber developers. It is designed to be cross platform and flexible. There are several projects to make this happen. oapr is the platform abstraction layer. oajabber provides a flexible c++ api to the XMPP/Jabber protocol and its extensions. xpoa is the primary UI layer that integrates into the XUL/XPCOM framework.
xpoa is an XPCOM wrapper of oajabber. It provides XMPP/Jabber support for the mozilla platform.
aether will provide a XUL interface to the XMPP/Jabber network. Currently, it is pretty void of functionality, so stayed tuned.
