Cyrus Caldav Murder integration

[Jean-Christophe Delaye]

Hi,

After successfully tested Cyrus IMAPD v2.4.17-caldav on a "stand-alone" 
Cyrus IMAP server, I wonder how to integrate "CalDAV" features in our 
running Imap systems.
We're currently using 2 murder hosts and 4 backend servers, running in a 
cluster (Solaris) environment. Users mailboxes are distributed on 4 
backends and I plan to offer caldendars to those users.

I understand that the CalDAV module will automatically create the 
required calendars for a user the first time that the user authenticates 
to the CalDAV server; but what's happen if mailboxes are located on 
different backends ?

- Do I have to configure CalDAV server only on the murder agreggator hosts ?
- Is there (or in the future) such a proxy mode for http services (or 
referrals like sieve) ?
- Or shall I consider using a "separate" Cyrus Caldav server acting as 
stand-alone calendar server with LOCAL mailboxes containing ONLY CAL 
information?

Of course I'd like to published only one calendar url for all.

Thanks.
