Here's a step-by-step that uses texi2dvi[fn:1]:

o Download a bibliography file:

  cd /home/nick/lib/bibtex
  wget -nd http://ftp.math.utah.edu/pub//tex/bib/linux.html
  mv linux.html linux.bib

o Set the BIBINPUTS environment variable in .profile (or similar):

  BIBINPUTS=/home/nick/lib/bibtex:$BIBINPUTS
  export BIBINPUTS

o Set org-latex-to-pdf-process in .emacs (or similar):

  (setq org-latex-to-pdf-process '("texi2dvi --pdf --tidy --batch %f"))

  The --tidy keeps all the intermediate files tucked away in a subdirectory.
  You can use --clean instead if you want automatic cleanup of intermediate
  files.

That's all for one-time setup. There is no problem with bibtex/makeindex
security because all the output files end up in a subdirectory and (I guess)
texi2dvi uses relative pathnames.

Here's an org file with an index and a bibliography that is properly exported
to PDF with the above setup:

--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{makeidx}
#+LATEX_HEADER: \makeindex

#+LaTeX: \bibliographystyle{plain}

* this

#+LaTeX: \index{foo}
is a test of foo \cite{Torvalds:1999:LE}

#+LaTeX: \bibliography{linux}
#+LaTeX: \printindex
--8<---------------cut here---------------end--------------->8---

Footnotes:

[fn:1] My egrep does not choke on the suspect [A-z] pattern that
texi2dvi uses, so I don't need Karl Berry's patch - if your egrep does
choke, the patch just changes the pattern to [A-Za-z] which although not
exactly the same, since it omits a few punctuation chars that come
between Z and a in ASCII[fn:2], is good enough.

[fn:2] The pattern tries to recognize legal drive names on DOS/Windoze,
and these characters are *legal drive names*!! We have Novell to thank
for that though, not M$. OTOH, if you are on Windoze and have a drive
named `[', watch out ;-)
