Family-wide view: show all upcoming bookings and events for all family members in one place.

Our membership is organized around families - with one or more adults and zero or more children. I suspect this is fairly common. We have had requests from members for a calendar view of some sort that can show a primary adult family member a calendar view that includes all the events/registrations/bookings for the entire family in a single view, and in addition, a full-family ICS calendar feed. Maybe even a Widget. This is currently not possible, and makes family planning difficult and cumbersome, having to manually examine each individual family member's bookings separately. We currently do now allow our family's children to book; parents must do so on their behalf.
