Does anyone have org-caldav working with the new Google endpoint or Zimbra? The former errors out (there's an issue on github, but I don't want a github account to ask there), and the latter uses a different URL scheme...
Zimbra's URL scheme is https://server.example.com/dav/username/calendarname with a calendarname is Calendar. Special-casing org-caldav-events-url for my server appears to work. Feels like that function could be over-ridden per server / target org file, but I'm not quite sure what the right granularity should be. Hm. Perhaps having each synced calendar in a separate org file might work. Each org file could set some file-wide parameters like calendar URL. -- Jason, who no longer has relevant papers on file...
