How about we just describe hurricane/wind noise through the use of 
some sound nodes?
Re: privacy... imagine some sound cancellation object
like the ones in real life people use on planes to 
get rid of the background noise!!! ( I don't really 
see this as being a node).
Anyhow, really I see that a lot of our initial work on 
this should be inspired by the work that's already
been done with camera and lighting nodes.
Thus I would expect some kind of allowance for
   DIRECTION!
I also appreciate the notion of sound
   ABSORPTION/TRANSMITTAL  through objects.
Thus, privacy might be handled by sticking
some transparent box around your group with !0!
sound transmittal.
It'd also be great to see some facility for 
looping sound files etc., but that might be more
for 2.0.
BTW, uh whatever happened to you (was it Tony
and Mark?) posting something on those four issues
you wanted to resolve on 1.0  (I remember
text, MIME, ...).  I haven't seen
anything about that yet? :)
