This is indeed a big plus for OpenAL - if we use our own sound system we'll have to reimplement DSound3D features. It fits the "sit on the shoulders of giants" - use existing infrastructure instead of reinventing the wheel, which is usually considered good software engineering practice.

The same can be said if we have our own sound system. Its "we have to lift a finger" vs "we have a sound infrastructure that matches windows perfectly"

Considering that it takes years to get a third party project fixed and the fix shipped to users I'd rather fix Wine. (Yeah, I know you're maintaining Linux OpenAL, so that would make fixing Linux OAL much easier if needed - but not getting it shipped)

They don't seem to care about 50-line opengl apps that cause kernel panics or crash the window server reliably. As bad as it sounds, on the apple side you either have to live with their bugs for a long time or abandon the platform.
(As an interesting factoid, the GCC developers don't work around bugs in the host's assembler and linker toolchain. Except on OSX)

Your OpenAL software implementation might help there. If it works on OSX we'd have an alternative we could point users to.
