maybe im missing it but isnt this NODE_ prefix thing only used once in here? I didn't read this whole thing throughly but seems like this is supposed to be similar to an earlier patch I had submitted, where all non-internal messages were simply re-emitted, but that was with a simple `switch()` this seems a bit extreme for little gain
