I found yet another great way to publish iCal calendars today: PHP iCalendar.
It's fast, easy, and requires only that the server support PHP, which is great for those of us with 'virtual host' style web accounts who want to publish iCal data. Exported calendars are parsed into HTML by the package, as well as making a webcal:// link and offering the calendar for static download (as an .ics file*).
With a bit of HTML/PHP work, you can customize the output to look however you'd like. In my case, I wanted to just focus in on three days next month, which was simply a matter of rearranging parts of a template.
Users can subscribe to the calendar, sync it to a handheld, and have a portable conference schedule (how's that for connected?). Since the calendars are just kept in a subdirectory, adding and indexing them is a cinch. For keeping your published calendar up to date, the previously mentioned CalSync can automate the process.
Note: Adding the line AddType text/calendar .ics to an .htaccess file will insure users are prompted to download the calendar source, and not display it in the browser.
