Apple Thoughts: iCal and Google Calendar Together At Last

"The Google Calendar team is proud to announce the public release of our support for the CalDAV protocol. You can now use Apple iCal with your Google Calendar, so you can work even when you're offline, sync almost instantly, respond to invitations from others and see the free/busy data of your friends and coworkers."

Now that's pretty cool, and on top of it, Google even has Calaboration, an iCal configuration tool, available just to make things go a little smoother during your setup. If you're one of those "everything in the cloud" types, this isn't a bad application and to top it all off, it's free!
