title: CalDAV Client for Windows/Linux/OSX/Android
body: <p>Is anybody aware of any CalDAV client for Windows/Linux/OSX/Android that implements MKCALENDAR request and reports defined in RFC4791 (CALDAV:calendar-query, CALDAV:free-busy-query etc.)?</p>
  
  <p>I've tested a few clients, but they use CalDAV server as a simple WebDAV storage and doesn't allow to perform advanced requests.</p>
