Customer Group Based Event Calendar

I have not been able to find an event calendar that allows me set permissions by customer groups.
Does anyone know of a calendar that does this?

My Needs:
- Customer Group Permissions
example:
- Customer Group 1 (has access to category a,b)
- Customer Group 2 (has access to category a,b,c)
- Customer Group 3 (has access to all categories)

- Categories (ability to change colors)
- WYSIWYG Editor
- Must be logged in to see the calendar
