Anyone is welcomed. I'm now waiting for response from Thomas Sailer
(mentioned by Alan Cox) which probably works on same thing (new sound
driver). Maybe we can join to one project.

Good project. I didn't see sources, but this is probably one of thing
which can be located in API library.

I agree. I think that API can allow exlusive access to device (for
mmaped access or for recording) or shared access (or something like this).
