Yes I could do that, but given that I'm storing the result in the user
preferences, and the user preferences can store dictionaries but not objects, I
was hoping to stay with dictionaries.
Maybe I should try inheriting from NSMutableDictionary or something.

Would that mean observing every single dictionary in the array and adding and
removing observers as the array expands and contracts? Sounds fiddly.

I'm a bit vague on how a DataSource and an ArrayController work together. Do
you choose one or the other? In any case, it sounds like a fairly fiddly option
too.
