You could use Config::handleEvent() to translate Equalizer events to OSG events and add them to the EventQueue I guess. I'm not sure how you can get the EventQueue of the viewer. The viewer has a window, which is a osgViewer::GraphicsWindow, where you can get the EventQueue from it seems. We use a GraphicsWindowEmbedded as the GraphicsWindow, so that OSG re-uses the context provided by Equalizer instead of creating its own window. Not sure if that already provides an EventQueue, maybe you need to derive from it. Anyway, I think this is a nice idea and would simplify things.
