While I agree with the above, it doesn't really address Johnny's
question, which is which open source calendaring projects can compete
with Google calendar for users' ease of use?  If I give my users Zimbra,
and they hate it, then what?  For simple email use, there are plenty of
clients which can talk IMAP/SMTP to a linux server, but the options for
calendaring (and ''groupware'' in general) are much sparser.

It's a hard question, and each organization needs to weigh their privacy
concerns against their users' requirements.
