Well said. I feel that too many people today have forgotten (or, more
likely, never learned) these lessons from history. People give away
their personal and supposedly private information too easily and, I feel
certain, will come to regret it (some already have come to regret it).

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.

Just to chime in, I'm using Fruux.com for a client, and while it's not
per se an open source service, it works really really well and uses open source
protocols for its operation (CalDAV and CardDAV). They also have great central
administration, even if it's all local accounts. They use SabreDAV as the
foundation for the service, hence I think it's worth mentioning.

Zimbra's calendaring component is also a CALDav compliant server. Users can
also share their calendars either via the zimbra web client(public, or
restricted to an email address with a password), or exporting the calendar to an
ICS file. CALDav compliant calendar clients like Apples calendar app on Mac and
iOS can subscribe or connect to the zimbra server using its
https://zimbra.example.com address. The Zimbra web client interface for using
and managing calendars is just as easy to use as googles calendars.
