Eclipse EventAdmin to dBus Bridge

In Eclipse RCP (and AFAIK OSGi) the premier communication mechanism *inside* an RCP application is the EclipseEvent Admin. Ideally there would be an EventAdmin-Zeitgeist Bridge, so Eclipse applications simply could talk to the EventAdmin and a listener would listen to "Zeitgeist" messages (Topic configurable) and propagate them to Zeitgeist.
The other way around would be cool too, but not that urgent.
I would defer buying my tablet and put the funds up as sponsorship (I know its not much since it isn't a corporate pocket). I can clarify EventAdmin questions.
