Do you really want to add them to the tree as the user expands it, or
do you just want to fetch them when the controller asks the model for
them?

Here is a sample project which uses NSTreeController to present the
filesystem through an NSBrowser. (I wrote it to demonstrate some bugs
in NSBrowser bindings in Tiger, which have since been fixed.) Of
course, I do not pre-populate some model object with the whole
filesystem; instead, the code just fetches directory contents as and
when they are needed. This sounds akin to what you need; hope it is
useful.
