Ok, thanks Peter, that finally gave me a reason to fix some code in 
MuMaMo to make these things simple. I have just uploaded a new beta of 
nXhtml here:

  http://ourcomments.org/Emacs/DL/elisp/nxhtml/beta/

If you use that beta with the following little code you will get what 
you want I believe:


(mumamo-easy-make-chunk-fun mumamo-test-lua-chunk
  "\\startluacode" "\\stopluacode" 'lua-mode)

(mumamo-easy-make-chunk-fun mumamo-test-MP-chunk
  "\\startMPcode" "\\stopMPcode" 'metapost-mode)

(define-mumamo-turn-on test-lua-and-MP
  "Just a quick test with lua and MP."
  ("lua MP test" context-mode
   (mumamo-test-lua-chunk
    mumamo-test-MP-chunk)))

Though I don't have lua-mode and context-mode here so I have not tested. 
Do you want to test?
