Free iCal Publishing

The Mac iCal program is very cool, but it's even cooler if you can publish your calendar so others can subscribe to it. By default iCal wants to use the $99/year .Mac, which I don't have and don't see a value in for myself, however I found a free site that you can use to publish your iCal, iCal Exchange (http://www.icalx.com/)!
