Provide Improved Centralized Backup for Team Calendars

Backup area in the Team Calendar portion of the Admin Console. A user would be able to check a box next to all calendars that you want to backup and back them all up at once.

It could create XML that is just an export of the calendar data (if that would work) or it could create iCals and zip them up. If this admin feature existed, it would be even better if it could be setup as a cron-job so it wouldn't have to be done manually.
