I'm not sure it counts as an Open Calendar, but Google Apps might do
what you want.  There are also some PHP icalendar programs.  I haven't
tried them for a while.  but search for php and ical.  One is
phpical, but it was fairly limited, and unless it's improved in the past
couple years, you might do better with another php ical solution.  Open
Groupware is another one.  I think Sun has a java-based calendar program
as well, and I think it's open source, though I'm not sure.

Another thing that I tried is plain ol' IMAP with a thunderbird
extension called sync kollab or something like that.  It might be a good
alternative as well.
