Very nice! I've been hoping for this kind of functionality for a
while, since I'm really struggling to organize some text-mass produced
by myself over the years, and it seems, that with this I can
re-organize largish LaTeX-documents with relative ease. (For some
reason, the order in which a text is naturally written may not be the
one that is most interesting to read...)  A quick test drive gives ok,
the document is exactly the same (tested with diff) after having gone
through the conversion back and forth.

I think it is a good thing to keep this separate from any of the
org-mode export functions. As far as I can see, the main use for this
is the editing of already existing LaTeX file (as in the case of the
original request), where you have to keep the file as closely
resembling the original as possible.

Also, this does not seem like something you use all the time when
editing LaTeX-files, but more like a tool very handy for reorganizing
and restructuring your work, i.e. not a replacement for
org-export-latex, but a tool to integrate existing material to the
new, exciting org-mode work flow.
