PUBLIC MARKS from nhoizey with tags caldav & calendrier

Cosmo is a calendar server. With your favorite calendar program (Chandler, Apple iCal, Mozilla Sunbird, or any other WebDAV or CalDAV enabled client), you can share your calendar with other people by publishing it to Cosmo. Once your calendar is stored on the server, you can give permission for others to subscribe to it, and even modify it if their calendar client allows.
