But Windows does have a scheduling service as well.

I'd just use the demon of the platform.  You can abstract away the
different backends with one class or one set of classes per platform.
In fact, this seems like a very valuable gem to me.  It would provide:

- a means from Ruby to reliably schedule tasks
- a unified frontend and convenient scheduling language (might be
tricky but rewarding)
- maybe excute all jobs as Ruby programs or alternatively invoking a
binary (which also would mean a script with proper shebang)

Kind regards
