Ability to control witch event types can be added to a given calendar

When creating a new calendar I would want to restrict what types of events can be added to this calendar.

For example: When I create a new calender containing JIRA Releases and FixDates I do not want other user to add ther leaves in this calendar.
Ther might be other calendar for this. But the possibility to add types of events to the wrong calendar might cause unexpirienced users to add the wrong events into the wrong calendar.
