just $.02 -- there are users who want to use ardour but don't need
zero-latency performance.  for instance, i produce small radio
documentaries and ould like to do this using free software; ardour is
the obvious choice, but i won't be recording on my computer -- i have a
handheld device i use for all recording, and then upload the resultant
mp3 files onto my computer for editing.

i think my use case applies here as well.  most of the time i'm
listening to mp3's; sometimes i do audio work, in which case i want
ardour to run unproblematically without uninstalling pulseaudio or
