What is the best Shared Calendar implementation for machines running OS X?
For a small office, you may be able to get away with using BusyCal. It works well for sharing calendars with a small workgroup. You can turn your co-workers calendars on or off so you can see them, or not, depending on your need to de-clutter your calendar. It's worked flawlessly for us with MobileMe calendar sharing, or you can set up your own CalDAV server. Free trial, excellent support. I'm a big fan.

  MobileMe: Not really shared calendar because I can't easily see a coworker's schedule.


I think I need more info, as I have no problems viewing the shared schedules of the other people on our system.
