[feature-request]

I would also like this.

I may have to try out mmm-mode.

One solution is to use M-x latex-mode, then M-x orgstruct-mode, but headlines lose their syntax highlighting.

There is also a blob from [[http://stackoverflow.com/a/25048304/2533127][org-mode buffer latex syntax highlighting - Stack Overflow]], but I've so far only improved it to the following state:

#+BEGIN_SRC emacs-lisp
(font-lock-add-keywords
 'org-mode
 `(("\\$.+?\\$" . font-lock-keyword-face)
   ("\\$\\$.+\\$\\$" . font-lock-keyword-face)
   (,(concat "\\\\" "\\["       ; \[
             "\\("              ; \(
             "." "\\|" "\n"     ; .|\n
             "\\)" "*"          ; \)*
             "\\\\" "\\]")      ; \]
    . font-lock-keyword-face)))
#+END_SRC

So I now get some syntax highlighting on articles written in org like

#+BEGIN_SRC org
$$ W_{net} = \Delta KE. $$

On the other hand, the $i^{th}$ contribution to the work due to the $i^{th}$ force is /always/ 

\[
W_i = \int_{\textbf{a}}^{\textbf{b}} 
      \textbf{F}_i \cdot d\textbf{r}. 
\]
#+END_SRC

It's a little broken, for instance it doesn't react to changes in the buffer.
