I was thinking that an OpenAL plugin would be doable, and could either
return an audio sink or an AudioStream.

Going the OpenAL route would also pave the way for an osgAudio
library, as the OpenAL dependency wouldn't change as one migrated
osgAudio into the core.  Go for another audio solution and one would
have a more complicated evolution of external dependencies.

I'm going to experiment with OpenAL at this end how things go.
