Are you concerned about making this easy to install for other users? While that's a good thing, I think you're seriously overthinking things. If users have to set up a cron job to make this work, they'll have to edit code anyway. Just tell them to install the module via the normal mechanism or add a use lib line to their code.
(As a side note, prepending "newbie" to your post subjects is useless; it adds no information of value.)
