nsoutlineview

I have an NSTreeController (supplying content to an NSOutlineView). I'd like the top-level objects to be of one class, and all other objects (so, children at any level) to be of another. What's the best way to go about this?

I'll need to somehow change the behavior of at least add, addChild, insert, and insertChild, I suppose. I was hoping, though, to find a simple way to account for this in only one location, rather than changing four separate methods.
