Well, the question is on the goal. I would use it like that:
- you are required to poll to get notified of changes
- optionally the server can provide UDP notification
In practice I would set my client to poll every 2-5 minutes or so,
which works great in the cafe or at home where the connection is slower
anyway, and if I'm in the office I can get almost instant updates using
Sounds OK for me.
But as mentioned in the draft we probably should leave that out of the
CalDAV specification? I guess this should be an additional draft.
