Others have been very helpful. I just wanted to mention that I have been
interested in working on a dbus interface for Octave, but nothing exists
yet that I know of. Let me know if you are interested in helping,
brainstorming, designing, funding, or otherwise.

Octave's Python interface is in development but is fairly functional at
the moment. Using it you might be able to launch some kind of dbus event
loop from within Octave. However there are no facilities to call back
into Octave from Python yet.
