I'd like to hear some suggestions for shared calendaring. The users are using Outlook. We can do Exchange if needed, but they aren't using AD right now, and so they would need to do a big move just to get the shared calendaring. If you know and use another solution then let me know (Linux based or not).
They have already expressed their dislike of web-based shared calendars. (Honestly, I don't like them either.) All suggestions are welcome!
