you could also try redefining the export of a ref link like this.

#+BEGIN_SRC emacs-lisp
(setf (elt  (assoc "ref" org-link-protocols) 2)
      (lambda (keyword desc format)
        (cond
         ((eq format 'latex)
          "\\vref{keyword}")
         ((eq format 'html)
          (format
           "<a href=\"%s\">%s</a>"
           keyword (or desc ""))))))
#+END_SRC

I am not sure if that is the kind of html export you want, but you could
adapt it to something else.
