I'm about to do almost exactly that with a site I'm doing - though it's for a radio station, and they want the schedule of programmes to be automatically added every day or week. I haven't implemented it yet, but what I think will happen is that I will have a folder called Programmes or something similar at the top level, which contains all the shows in folders for each day. Some time every week, a cron job will copy the entire subtree to a place on the live site, and change any dates inside the objects as required. That's what I think at the moment, but I might change it later when I actually get round to doing it (which might be tomorrow). I will keep you informed and make any code I write available.
