CalDAV Calendar support

[soomuch]

Any idea if there was any conversation with Microsoft about Windows Phone 7 supporting CalDAV for calendar access. The idea is to be able to access different calendars from your phone without having your Windows Live account OR exchange account as the only method to sync with a calendar. CalDAV support would allow access to any type of calendars such as Google Calendar and other calendar servers out there. Just to list a few (iCal, DAViCal, bedework...etc). Since not everyone out there uses Microsoft services in order to access a calendar i was wondering if anyone is aware of something in the works.
