If KronolithICal means ical files shared over webdav, then personally, I
don't see that as a good way to do online calendaring.  It sounds a bit
like using mboxes shared over webdav for email.   As I understand it with
calendaring over webdav, you rewrite the calendar file every time you
change it.  You might have a 5-10MB calendar and every time you made a
small modification you'd upload the whole thing.  

CalDAV seems to me to be the emerging standard.

We'll be hoping to use a host of calendars including Thunderbird, iPhones,
Nokia Phones, Outlook, etc.  Most but not all will support CalDAV yet, so
we'll need to be careful about that.

Do you mean the Kolab 2 calendaring?

I consider Kolab a good email setup, based on cyrus, openldap and postfix
but I'll have to look in detail at the calendaring afterward.  At the
minute, my plan is to integrate davical or the apple calendar-server
myself.  Interoperability is key for us.

Understood, but (at least to me) it's preferable to have it packaged and
patched as part of Debian.  If there's a compelling reason, we can use the
OpenPKG version, but I would prefer well-maintained Debian packages.  I
presume, given the existence of this project, that I'm not alone.

Fair enough.  I appreciate your candour.

I'm trying to solve the server end first.  We will choose a webmail client
after that.  Horde will be one of the options on the table.

That's useful to know.
