Or they are using the VLC backend ... whatever VLC uses afterwards.

Either I missed or misunderstood something, or you forgot to take something into account: ALSA doesn't exist on OS X. So all those applications that rely on the ALSA API should be helped by something on OS X that puts the ALSA API in front of CoreAudio.

PulseAudio on OS X will not do that. It works that way on Linux because of the magic of ALSA.

No, I don't. I hope I didn't give the impression, but it was never my intention to claim that I was looking to cater to applications that do use the PA API.
Really, for all I knew PA was an alternative to ALSA on Linux, one that also happens to support OS X to some extent, while ALSA clearly does not. (At least it couldn't without a name change :)).

There are no (real) alternatives to ALSA on Linux - everything else is just a layer on top of ALSA. Same story on OS X, except that there are very, very few applications written for OS X that do not just use the CoreAudio API as-is - there isn't much middle ware on this platform. Even apps that can interact with JACK do so via its appearing to be a CoreAudio device.
