As we’re developing a Java & Jabber/XMPP (-> will become multi-protocol) based collaboration application at university, I just want to point out to its web page, as it will soon be available for private and then for public beta.
The Java 6 based Swing-Application Jake feels and looks like an native mac os-x application, thanks to support from MacWidgets, where one of our developers (Peter) is heavily reporting bugs and feature requests 😉
So in the meantime visit the Jake Website and/or the Jake Blog.
