It is very frustrating having two separate calendar systems.  As a user, I
would expect:
 -  to be able to add "To Do" items to the main Calendar, from the main
Calendar
 -  to be able to add "To Do" items in a list format as it is.
 -  to have "To Do" items show on my calendar, but have nobody else see
them.  
 -  Be able to see my meetings and my "To Do" items together (already
implied)
 -  The "Tasks" recurrence should support the same patterns as the Calendar.

Requirements:
1) Essentially, if a Task has an associated Date, it should be automatically
displayed on the Calendar in a distict way.  
2) To be able to add tasks from the Calendar, and have them show up in the
Tasks list.
