A friend of mine is switching to Mac from Windows and is looking for a groupware calendar. He's having trouble getting iCal to do what he needs it to. Does anyone know of a good groupware calendaring system for Mac OS X? Said calendar should:
- allow authorized users to manipulate each other's calendars
- have a good Mac-native interface
- allow publish and subscribe of iCal-compatible .ics files
- allow publishing of a "censored" calendar that shows subscribers what times are blocked out, but which doesn't reveal the actual events
- have all the typical calendar bells and whistles
- should not require an IT department to install/maintain it
