Find a way to suppress sending of meeting invitations on the CalDAV server when Evolution already sent one, or
suppress sending of meeting invitations in Evolution for calendars which are mirrored in a CalDAV server.
When storing a meeting and/or the server does not return an ETag, retrieve the possibly modified item from the server and store the modified item locally. Right now the more possibly automatically modified data on the server gets ignored. Depends on the engine improvements mentioned above.
