There are longstanding bugs from four to five years ago, all the way
back to the XO-1, that prevent collaboration from working when
aggressive power management (suspend) is enabled.  Most of those
never got fixed, as far as I know.  Lots of circumventions were
attempted.  Some bugs were closed despite not actually getting the
right fix implemented.  They're all still in trac.  E.g.:

  http://dev.laptop.org/ticket/4616
  http://dev.laptop.org/ticket/9535
  http://dev.laptop.org/ticket/10878
  http://dev.laptop.org/ticket/10363
  http://dev.laptop.org/ticket/10207 (closed because it still fails!)
  http://dev.laptop.org/ticket/7128
  http://dev.laptop.org/ticket/6818
  http://dev.laptop.org/ticket/6684

Back then, we were barely able to do the bugfixes needed to get to
minimal power when suspending the XO-1 when you close the lid.  Making
exotic features like collaboration work was way beyond what the team
was able to do.  Perhaps now is different?
