We’re interested in supporting this and in fact we already support some bits and pieces of this notification functionality (e.g. when someone invites you into a calendar), but unfortunately this is not a standard yet (it’s an Apple extension: https://github.com/fruux/sabre-dav/blob/master/docs/caldav-notifications.txt).
These change-notifications don’t seem to be supported for third parties at the moment.
We’ll keep an eye on this as Apple releases newer versions of its operating systems (iOS7/OS X Mavericks).
Repeatable tasks and alarms are fully supported, it’s just our webapp thats still lacking a bit in that regard. Adding this functionality to our webapp is of course planned.
