I looked at this, but then I ran across org-eval.el in the
org/contrib/lisp directory.  With (require 'org-eval) in my .emacs I can
put something like the following

<lisp>
(defun my-specific-function-for-this-file (org-tabl-cell)
  (format "%S"
	  (do-something-special
	   (read org-tabl-cell))))
</lisp>

in an org file and org-eval is nice enough to evaluate the code defining
the function upon opening the file, to display only the name of the
function in a special face, and to allow me to edit the function in the
appropriate mode with C-' (also works for ruby/shell/python/etc...).
Everything I could have asked for!

It nice to request a feature and find it's already implemented.

Thanks -- Eric
