if the laptop is suspending, that means jukebox is using less
than 15% of the cpu during playback, which is impressive.  i just
tried jukebox with this sample from wikipedia:

and cpu utilization is more like 50%, and suspend is inhibited as
expected.  can you make one of your ogg samples available?  feel free
to attach it to a bug against powerd.

i doubt it's ready, and i doubt it does what powerd does.  maybe
someday.

well, i hope it won't be necessary, and that powerd's cpu utilization
heuristic will work well enough.  but if not, see:
  http://dev.laptop.org/git/users/pgf/powerd/tree/powerd#n170

there's python code for this in bitfrost, as used by olpc-update, and
also unused (unneeded) patches against the Distance activity attached to:
