Ivor -

Sounds like BackgroundRb is a good solution for your problem.
You define scheduled jobs in a file /config/backgroundrb_schedules.yml
-- these will get fired off on the interval you set.

Here's what my backgroundrb_schedules.yml looks like:

  :class: :scheduled_publish_worker
  :job_key: :scheduled_publisher
  :worker_method: :do_publish
  :worker_method_args: scheduled workers require some args, so here you go...
      :start: <%= Time.now + 5.seconds %>
      :repeat_interval: <%= 1.minutes %>

This kicks off a worker that checks for pending publications every minute.

Note the :worker_method_args -- field. I found that if you do not
provide a value for this field your scheduled worked won't run. My
scheduled_publish_worker doesn't need any args -- so I provided a
placeholder value for :worker_method_args.
