pulseaudio...

Title:
  System mode: SHM avaliblity.

Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  Hello,
    Let start with the most basic, I fully understand that System mode is taboo and unsupported by upstream.  I understand there reasoning, well I don't get the part about "You shouldn't use system mode because we refuse to offer SHM support for it."  That's just the pot calling the kettle black.

  In any case I'm using PA in system mode because I haven't been able to
  use dmix for various reasons, the closest I got was after 5 or 6 hacks
  I got silence and surround sound was forever out of my reach.   I'm
  sure there are other vary rare cases where System mode may be the only
  logical option.  What I needed out of dmix was to mix sound from
  several users, libvirt and others.

  Regardless of why, you should just take it on my authority that I have
  good reason for configuring a system this way.

  Attached you should find my /etc/default/pulseaudio file, it clearly
  is configured to forcibly enable SHM.  However as the documentation
  suggests this feature is disabled in system mode.  I know X does SHM
  and it nearly always runs as another user, so it should be technically
  possible...  Politics and opinions aside.

  Would a patch for this be accepted into Ubuntu?
