In your search for a cron daemon (and there's quite a selection out 
there, some mimic the BSD-esqness of Slackware, some do their own 
thing), you might want to find one that mentions a layout like so:
	/etc/cron.hourly
	/etc/cron.daily
	/etc/cron.weekly
	/etc/cron.monthly
If the restrictions of the "appliance" won't let a proc operate 
outside it's home directory, this might be difficult.
P.S: I'm a slacker, so you might have better luck with "Dillion's 
Cron" ( http://freshmeat.net/projects/dcron/ )
P.S.S:  I'm heading home tonite, I'll prolly be up hacking away if my 
DSL hasn't been transfered to my new addy yet.
I'll send you my home email addy in a lil bit.
