I’ve released a Web application called iWebCal that can read iCal (.ics) files on any Web server and display them on the Web. Publishing with it doesn’t require WebDAV or a .Mac subscription, just access to a Web server. Access is through the iWebCal site, each calendar has a unique URL that you can bookmark or link directly to. iWebCal is located at http://interfacethis.com/iwebcal. Comments and suggestions are, of course, welcome and encouraged.
