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
