Google Calendar terms of service

I love the questions and facts I get from Calendar Swamp readers. One such reader alerted me that the Google Calendar terms of service limit use of Google Calendar to "personal or internal business use only." The reader is looking for an alternative that could be used to publish a Web calendar for business use. The catch is it has to be free like Google Calendar. I'm stumped. But I'm also thinking there are lots of public Google Calendars which are being published for business purposes. Do you know of any? Or of any that Google has asked to have taken down?
