I have facebook automated ad delivery system, that was written using facebook apps, javascript, and php.  For windows or Unix, it does require a webserver.  This app delivery system does not cost anything to post ads.  It only posts within the scope of your facebook friends.  I wrote this and use facebook apps for the entry point, and simulate a user entering data, it reads data from a flat file with a simple php based database system ( not sql ).  It can run all day, or only when you are at your shop.  Call for details.
