As others have said it would be highly useful to be able to use feeds and subscriptions from the calendars we're creating to be able to easily populate other formats like display panels with our events.

We work with a community group that shares our events to their calendar. With our old calendar we had an RSS/iCal feed that automatically shared our events saving us considerable staff time.

This feed option would be useful for other technology needs such as reservation panels outside event spaces that rely on a feed to present a schedule of events and reservations for a meeting space.
