since we aren't psychics, the daemon should have a configuration and script
place in /etc (/etc/pmu?).  the config would allow the user to control some
standard responses on how it acts internally. (like volume control, switching,
etc)  then the option to do additional things in scripts.  Given the potential
flexibility people may want, does this mean C is too static, and thus perl or
another more script-friendly language should be used?

If all goes well, we may eventually have a "apmd" for ppc.  any reason we
shouldn't try to use apmd as a framework?  have a so-called "apmd-compatibility"
mode where we can use the standard PC apmd as our frontend?  or does it not have
features like eth detect, so its not worth the bother?  (never had a pc laptop)

a few ideas from a peanut.
