Ruby starting / stopping a windows service?

Hello, I was wondering if it were possible for a Ruby on Rails program (I'm running with InstantRails 1.6) to start and stop a windows service. Pretty much, I'd want to write a Ruby script that would run every so often, perhaps once or twice a day. My boss would like it to run as a windows service on Server 2003... Anybody have an idea or have any pointers on this?

Thanks, - Jeff Miller
