Google Calendar adds CalDAV support

Google updated Google Calendar, adding CalDAV support. +1 SwampDrain point for Google.

I'm looking forward to the day when everyone who should supports CalDAV.

UPDATE: The Spanning Sync blog claims that calendars synced with CalDAV become read-only on the iPhone. Yikes!! I hope the problem is just the way Google Calendar implements CalDAV...and not a problem with CalDAV itself.
