LaTeX-producing code : how to export results to HTML/ODT ?

Dear list,

Org-mode offers the ability to create functions returning LaTeX results
: such occurrences are frequent with Sagemath, Maxima, Mathematica, R,
and even emacs's Calc...

Such functions can be declared has having LaTeX output, and the
resulting  =#+begin_export latex ...  #+end_export latex= block is
exported as LaTeX and end up in the PDF versin.

But such blocks seem to export *only* to LaTeX/PDF ; more specically,
they do not export to HTML nor ODT. In order to insert those results at
export, one *has* to print them *raw*. See the attached examples, and
compare PDF, HTML and ODT outputs of the enclosed zip archive
(necessary to avoid the wrath of the spam filter of my provider ;-
)...)..

Unless I am mistaken, this is the *only* way to export LaTeX exports to
HTML/ODT ; I am not aware of any option allowing to force such exports.
So a couple questions :
 * Am I mistaken ?
 * Are there more steamlined ways to get LaTeX in HTML/ODF/whatever-
   but-not-LaTeX ?
 * Wouldn't an option to allow these exports be a welcome addition to
   the export structure (or possibly to the various exporters) ?

Thanks in advance,
