I starting thinking about what this might look like in 2.5.

You might have mono sounds placed in blender like you might place an Empty.

You might parent this sound empty to an object for example a car sound
parented to the car.

The active camera would be the mic focal point for recording.

Done really well we would have sound textures for objects. Thus a metal room
would sound different that on coated with egg cartons or sound tile.

Sounds would be animated just like objects are.  (we already have this

They would have start and stop volumes and times as well as perhaps triggers
for the BGE.

3d sound would include the effects of the shape and size or the room and the
objects in it.

Out put would be in at least 5.1 if not even 10.2 file formats
but stereo would be a good start!

There would be tools both in the VSE and the node editor for sound. Perhaps
there would be a complete separate view for sound node work.

What else might be needed? How else would it look? Would the recruiting of a
dev for this be supported?

Why do we need all this? Because it is well know that good sound will make
people think you have good video when you don't. It will make a good video
great! Nothing looses an audience more than poor sound.

Listen to this!! (with headphones only)
