Thanks for info.  Just a quick glance, CUSE looks like a good
abstraction for this kind of things.

I've been thinking that the tunneling to an OSS-emulation daemon would
be the best way, too, and I actually made a similar hack (not based on
FUSE but own kernel module).

It was presented in SUSE Labs conference a few years ago.  And the
reaction by audience at that time was what Adrian showed -- why do we
need such a complexity at all?  Well, as long as we have OSS API and
its applications, we should keep supporting them in a good form.

Anyway, my implementation at that time was too hackish and I gave up
soon.  If it can be implemented in a generic framework like CUSE,
it's a good chance to merge to the upstream.

One thing I couldn't find in your code is the mmap support.
The mmap support is crucial for some apps, typically used for games.
Am I missing something?

thanks,

Takashi
