IMO, OS X desperately needs such a general-purpose scheduler service.
There's loginwindow's scheduler (which Software Update uses), and
cron, and the sleep/wakeup notification service, etc., and there's no
real unified, Mac-friendly way of scheduling stuff.
So if loginwindow's scheduler and/or cron are inadequate, please
consider writing something. :)
