All things considered, if you believe you can make a Jack Mode 
implementation that is
  1) Generic, i e, same code shared for all codecs
  2) Free from regressions for the end user never touching ALSA and just 
running PulseAudio with GNOME/Unity UI. That includes all volume 
controls still working, non-existing ports should not show up, etc.
  3) Bug free in other ways too ;-)
  4) And do this within a kernel cycle, i e, without a few broken 
kernels (e g Realtek multi-IO implementation caused some regressions in 
3.2 and 3.3)

...then I think you should go for it. But I would still see it as high 
risk. Maybe I should help testing somehow?

Then if PulseAudio doesn't support doing the retasking by default, then 
that's just something we have to work with in PulseAudio later on.
