In principle, this is the idea.  Before 6.33 I pretty much pushed  
every Org-mode
release to Emacs.  At that point, Emacs went into feature freeze for  
another release
(23.2, I believe), and therefore I had to stop updating.

Now it is time to get back into this - but I have not done it due to  
time
constraints.  It is not trival to push our changes to Emacs.

- Emacs now uses bzr, which I am not familar with.  I have installed bzr
   and pulled the Emacs trunk onto my machine - but I still need to test
   if I can actually commit using that setup.
   I wish Emacs had chosen git, because this is what I know reasonably  
well
   now, and because git is, from what I can tell, better.

- There are a lot of issues that need to be taken care of.
   1. The Emacs developers regularly make global changes o all code in  
Emacs,
      to make use of new features or to implement new conventions.
      I try to merge all these changes into my development version.   
Sometimes
      this is not possible, because the changes the Emacs developers  
introduce
      will not work for older versions of Emacs (like Emacs 21 or 22).
      Example: interactive-p and called-interactively.
   2. Because I am not as good with version control as I would like to  
be
      handwork has to be done, and I have been burned in the past  
several times
      because my changes reverted some changes made inside Emacs.   
This is a
      psychological barrier for me to go ahead and make the next update.

Nevertheless, I am planning to update Emacs again - but I am not sure
exactly when I will find the time.

If there is a volunteer who is willing to take charge of the
synchronization with Emacs, this would be absolutely great.  But it
would have to be a dedicated and careful person, who is willing to
patiently work through the issues.
