Almost.
"if we get everyone to switch to alsa, then everyone can share audio
interfaces".
"if we teach everyone how to use LD_PRELOAD and they accept it, then
everyone can share audio interfaces without even switching to ALSA."
"if we get everyone to switch to alsa, and they use the poll interface
via ALSA to control their workflow, and/or only read/write avail_min
chunks of data, then they'll be ready for their app to work in a
synchronous execution system, of which JACK is an example."
Just to keeps things complex, note that there is to stop a JACK server
from accessing a shared ALSA interface - remember, there is nothing
different in ALSA-using code whether its using a "hw" PCM device, a
"plug" PCM device, or a "multi" (subset) PCM device, or a "shared" PCM
device. the API is identical for all of them.
