Problem you are having

My proposal is to implement resources (calendars and addressbooks) can be shared by owners to other users.
And to be possible choosing readonly or writable mode for resource data being shared.

As comented #1333 (comment) SabreDAV supports calendars sharing (I don't know if also addressbooks), this part of proposal could be realized by integrating in Baikal GUI the action in an easy form.
