I believe it can be accessed/exported as iCal, XML or HTML.
Dr BS - yeah, free and useful. I use four calendars colour coded and combined (e.g., basketball shows up orange, of course) - a boardroom calendar shared with the others in the office, my calendar and a basketball one (both shared with my partner), and her calendar shared with me. Can be especially useful from here until the end of the year when you're juggling various social engagements, games, dinners with parents, holidays, meetings, functions and so on.
The good part about the shared calendars is they're centrally updated and pushed out to all subscribers. So if you are subbed to the 36ers calendar, and Fox makes them change a game time, it will get updated for you. Would be useful to have ones for all NBL teams, Fox games, 36ers events, etc.
