Hi Johan:

That's very nice.  And following along those lines...  For those who 
want to have ESS capabilities within latex-mode, do the following:

(require 'mmm-auto)
(setq mmm-global-mode 'maybe)
(setq mmm-submode-decoration-level 2)
(mmm-add-group 'latex-weave
               '((Sinput
                  :submode r-mode
                  :face mmm-comment-submode-face
                  :front ".*\\\\begin{Sinput}"
                  :back  ".*\\\\end{Sinput}")))
(add-to-list 'mmm-mode-ext-classes-alist '(latex-mode nil latex-weave))

Then, you will have ESS[S] in the R chunks (but for me, they are 
highlighted in cyan).  And, you have access to iESS[R] functions
through the menus, but you don't get the toolbar.  And, it seems
like it would be easy to adapt this to iESS[SAS].  But, you don't
get Soutput unless I'm missing something  Hmm...  Need to get back
to sweave for that I'm guessing.
