These are available for individual events. Is it possible to make these options available for "by category" or "entire calendar"? I've had a school ask this question as parents will want to download entire categories (for instance their child's class category) for the entire year. With multiple events every month it's too tedious doing it one by one.
For iCAL, I guess we can add support for whole category in the future. For Google And Yahoo, honestly, at the moment, I don't know if it is possible and could not promise
