1. That's very useful and makes .org file distribution much easier since 
configuration is self-contained. Thanks.

2. I find that it doesn't work. For instance, this buffer

---------
#+BIND: org-export-with-section-numbers nil

* one
something
---------

and this one:
---------
#+BIND: org-export-with-section-numbers t

* one
something
---------

  Export the same content, with section numbers. Only with this:
#+OPTIONS: num:nil
  can I export without section numbers.

  Running org 6.29a on latest Emacs from CVS from today. I get no other error 
messages.



3. I found it created one problem with custom time dates. I can't export this 
buffer:
--------
#+STARTUP: customtime
#+BIND: org-time-stamp-custom-formats '("<%d.m%m.%Y>" . "<%d.m%m.%Y %H:%M>")
# (setq org-time-stamp-custom-formats '("<%d.m%m.%Y>" . "<%d.m%m.%Y %H:%M>"))

a date:

<2006-03-25 sáb>
--------

  It fails with:

Debugger entered--Lisp error: (wrong-type-argument arrayp quote)
  substring(quote 1 -1)
  (concat (if inactive "[" "<") (substring tf 1 -1) (if inactive "]" ">"))
  (format-time-string (concat (if inactive "[" "<") (substring tf 1 -1) (if 
inactive "]" ">")) (apply (quote encode-time) time))
…
  org-translate-time(#("<2006-03-25 s\x00e1\ b>" 0 1 (fontified t) 1 2 
(fontified t display #("25.m03.2006" 0 11 ...)) 2 3 (fontified t org-dwidth t 
org-dwidth-n 3 display #("25.m03.2006" 0 11 ...)) 3 15 (fontified t display 
#("25.m03.2006" 0 11 ...)) 15 16 (fontified t rear-nonsticky (mouse-face 
highlight keymap invisible intangible help-echo org-linked-text))))


  It fails only if I have that #+BIND line.
  You may eval or not the (setq), as needed; it's there only to test.



4. Being able to change any variable is dangerous. „Local variables“ in Emacs 
have a confirmation dialog which asks whether you really want to change them; 
org may need something similar if it reimplements local variables.
   Restricting changes to variables whose name is org-.* probably doesn't 
prevent code execution, and anyway the good thing about #+BIND: is being able 
to change anything. So maybe a confirmation dialog can be used, or a switch.



  Thanks
