Yup. 

Remap the % to do this if it's sitting on a parenthesis, and to call
self-insert-command otherwise. Granted, this means you'll never be
able to insert a % in front of a parenthesis without extra keystrokes,
but how often does that happen?

;; for simulating Vi's % capability
(defun match-paren (arg)
  "Go to the matching paren if on a paren; otherwise insert %."
  (interactive "p")
  (cond ((looking-at "\\s\(")(forward-list 1)(backward-char 1))   
        ((looking-at "\\s\)")(forward-char 1)(backward-list 1))
        (t (self-insert-command (or arg 1)))))
