I've tried using NSAttributedString (in the hope I can use a special NSURLProtocol to intercept the hyperlink), but it takes four clicks to get there (row select, cell select, edit, and link-click). I've tried numerous tricks but to no avail.

You'll have to implement the logic in an NSTableView subclass. Override -mouseDown:, grab the cell at the mouse location, look at the cell's contents to see if you hit a link, and if so, do your link stuff. If not, call super for the default selection/tracking/editing behavior to take place.
