Andrew,
[good news, esp. the time-line]
Let's hope I can stick to it :-P. It's looking good, though.
OSSv4 (complete)
Do you specifically use OSS *v4* functions not available earlier? (I'm not familiar with OSS4, even though I consult their docu online and hope that what they write also applies to my machine with OSS v3 (Ubuntu)).
I wrote it following the OSSv4 spec and using an OSSv4 implementation, so I suspect it won't work on OSSv3. I thought about supporting OSSv3, but I think it's not worth the effort -- that's a really old version that, when written, didn't support multiple clients simultaneously, had no mixer, etc. OSSv4 has a lot of features that make the driver much simpler.
Further, I think only Linux is still stuck on OSSv3. I looked at a number of other operating systems, mostly BSDs and Solaris, and they all use OSSv4 by default. So I think Linux users should be covered by ALSA or PulseAudio (or perhaps JACK), and the much-more-pleasant OSSv4 is available for BSDs and Solaris. If a Linux user really wants OSS, I think they should probably upgrade to OSSv4 anyway.
I could look at making it OSSv3 compatible, but I just think it's not worth the effort of supporting such an old and cantankerous API.
