You all seem to forget that dmix is in userspace in a different task
too.

No evident gain?  Wow.  What about:
- stopping crippling the OSS api

- having a real kernel api for which you can make different libraries
  depending on the need of the users

- stop making a fundamentally unsecure shared library mandatory

- opening the possibility of writing plugins to people without a PhD
  in lattice QCD.

and that's just a start.

  OG.
