Using Jabber as a communications framework

Adrian Sutton asks about using Jabber as a communications framework for developing a bug-tracking/QA application. Two items immediately spring to mind.

• ACME: Toward a LL Testing Framework for Large Distributed Systems
  - Dana Moore and Bill Wright
• ejabberd and J-EAI - which uses it as it's message bus.

I haven't had any experience with jabber except as a casual user, however these are projects that have caught my eye as things I would like to investigate when/if I ever have time. So Adrian, if you do check them out, let me know how you go :).
