Because of the way that a document window's title changes instantly when its file is moved in Finder, apparently Apple has this already built in to NSDocument. Does anyone know how to hook into that, ahead of setFileURL:?
A bit of lateral thinking:
Take a look at -[NSWindowController windowTitleForDocumentDisplayName:]. However the document chooses to manage its URL, it seems likely that this method is going to be called whenever it does change. You could use this invocation as a signal that your code should go check the URL.
