Comment(by cjb):

 Oh, forgot to answer pgf's questions:

 Replying to [comment:9 pgf]:
 > what does sugar do now?  it just writes to /sys/class/backlight/dcon-
 bl/brightness, doesn't it?  can ohmd just use inotify to stay informed of
 writes to that node?  (inotify works correctly on it -- i just tried with
 inotifywatch.)

 No, Sugar can't write to /sys because it doesn't run as root.  Until
 recently it sent a dbus message to olpc-hardware-manager; now it sends a
 dbus message to OHM.

 > (i don't like the idea of adding a private protocol to control
 brightness -- makes it that much harder to integrate other tools.)

 The other tools can use /sys, I think.  I can't think of a better
 alternative.
