Hi Jason and Robert,

Okay, I didn't know what you were expecting. So now I'm aware of it!
I'm just a bit embarassed by the fact your work *may* be a duplicate (well, kind of) of what's inside osgAL. Anyway, I guess osgAudio would integrate both your work and osgAL.
Good luck in making your plugin work!
