Not sure this totally fits under the "hosting software" category, but I'm sure that someone has run across what I'm looking for in an autoinstaller script somewhere. I'm looking for a simple PHP calendar script that will let me update the calendar by using a program such as Mozilla Calendar or Sunbird (leaning towards Calendar, as I've run into some bugs using Sunbird on someone else's project a few months ago). Also, how exactly can I setup Mozilla Calendar to publish to the website?

Thanks,
Josh

Try iCalendar off sourceforge (http://www.k5n.us/webcalendar.php)

"A calendar server that can be viewed with iCal-compliant calendar applications like Mozilla Sunbird, Apple iCal or GNOME Evolution or RSS-enabled applications like Firefox, Thunderbird, RSSOwl, or FeedDemon, or BlogExpress."

Another item on that page says that it will read/write sync with Sunbird in the current development release, there is a link in the wiki about setting this up.
