I don't think this is something that ESS needs to get involved with.
This is something that users should be doing one way or the other.


In .emacs  (this works for xemacs, emacs uses something else similar)
I have .emacs check to see if a gnuserv is running elsewhere, and if
not start one up (except at-home).  All you really need is (gnuserv-start)

(defun any-gnuserv-running-p ()
  (or (gnuserv-running-p)
      (let ((client (exec-to-string "gnuclient -batch -eval t")))
        (cond ((string-match "^t" client) t)
              ((string-match "^gnuclient:" client) nil)
              (t nil)))))
(defun gnuserv () 
  (interactive) 
  (if (not (any-gnuserv-running-p)) (gnuserv-start)))

(when (not at-home)
  (gnuserv))


Then somewhere in your s.init: Do

 options(editor="gnuclient")

Then do something that uses splus editor.

 fix(fix)

And splus pops up a xemacs window editing 'fix' in a temporary file
named fix$$.  Unfortunately, the fix function doesn't do anything to
tell xemacs that S-mode should be used for the function.
