In my pursuit to not renew my .Mac subscription this year, I decided to install PHP iCalendar. Since we use only SFTP on our box, and none of the the iCal FTP apps out there support that protocol, I was left with publishing from iCal via WebDav. After I confirmed with him that WebDav was available on our box's installation, Jim, our sysamdmin, walked me through setting up authentication for publishing and viewing. This was not without its little hiccups.
Being the brilliant guy he is, Jim soon figured out the issue, and now I am happily publishing my calendar to the web. A quick bookmark, named oh so originally "Cal", in Safari's Bookmark Bar, and I'm set.
