>>> After I started my testing, I did run into problems when I tried to re-install pulseaudio and then remove it, but the PA problem was unrelated. Ubuntu said there was a PA bug, and issued a fix. After I applied the fix, no more problems working with pulseaudio removed. So the whole thing was sort of a red herring.

I've had a few users report crashing in steam games as a result of 
pulseaudio: https://bugs.launchpad.net/bugs/367379  -- do you think this
