You can use packages,  just use the nightly packages.

In short: iCal is a brain-dead standard for sharing *CALENDARS*.  In a
group of any size or complexity "sharing calendars" is simply horrible,
what you want is a "shared calendar".    A subtle but very significant
distinction.

Well, the difference is a whole lot more than that.  CalDAV works with
*EVENTS*.  IMO, the best explanation in layman terms is that CalDAV is a
"groupware" technology and iCalendar is a PIM technology.

This is true of both iCal and CalDAV;  the only way around this is some
kind of server-alerted-sync (which maybe the CalDAV spec provides some
specific provision for,  I've never seen it mentioned anywhere).

Yep,  when OGo was released in 2003 I actually had the papers on my desk
to get a trial of Lotus Notes/Domino.  OpenMail which we had also been
looking at had just closed up shop [ I think it is back now as Samsung
Connect or some such;  but who cares!  We have an Open Source
solution. :) ]
