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.
