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 
UDP.
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.

Greets,
