Awesome, thanks!  In my case I want to track a particular line, so it would be

   (set (make-local-variable 'header-line-format)
        '(:eval (save-excursion
                  (goto-line 18)
                  (move-to-column (window-hscroll))
                  (buffer-substring (point) (line-end-position)))))

Thanks again,
Lee
