Something CUSE based, for example, or one of the existing LD_PRELOAD
hacks. Replacing the OSS emulation with something that throws the data
back out to userspace would also work, I guess.

Specifically since they are in kernel they don't (and can't really) play
at all with any userspace ALSA stuff such as DSP, PulseAudio or the
various network and wireless I/O drivers that are implemented in
userspace. They also cause pain for the standard ALSA drivers since the
mismatch between the OSS and ALSA configuration APIs results in ALSA
drivers having to jump through hoops for the benefit of the OSS
emulation, and the OSS configuration model is just too limited to
express the control available on many modern systems.
