No, no, I dont wanna create yet another one. I'm just trying to find
out, whether the exist PA API could become one (as it's AFAIK already
crossplatform), even for cases where no audio server is running at all.

That would imply, that it wouldn't be possible to make PA itself cross
platform (which, according to the website, it already is).

That would be more the 'not invented here'-syndrome. Eg. on FF that's
my impression - they already support PA as a backend (along w/ others)
and now dropping ALSA - that implies, PA API is sufficient for them.

Probably. But that would even more call for building that *API* out of
an existing, working crossplatform solution. All it now takes is
separating out the daemon specific stuff from the generic, move the
API (IOW: headers) into an own package (similar to xorg-proto-*
packages) and let PA sit ontop of that. Then we would also have a
working solution for vast majority of usecases. Now, if somebody wants
eg. an ALSA-only (completely serverless) backend, he already has a
good starting place and cut out all the stuff he doesn't need.

*MAYBE*, with a bit more in-depth analysis, we could even find a way
for using the same API for PA's backends themselves. But that's a whole
different exercise. (not a at all on my scope right now).
