Google Calendar & iCal
Google's web-based Calendar application should now support iCal integration, the company has announced. The feature comes by way of support for the CalDAV protocol, which in turn allows access to a calendar via WebDAV. Users of the Google app should now be able to edit a calendar in iCal and have it sync with their online schedule, as well as vice versa. Changes are applied whenever iCal is able to go online, or a person signs into Calendar.
The CalDAV feature supports sync between multiple users and devices, but is at present only editable on a computer only through iCal. The technology also requires the creation of a new CalDAV server account for every calendar, and the typical re-ordering of calendars is non-functional. In that regard, syncing with multiple Google calendars prevents switching between calendars in iCal.
