Thanks for sharing, and sounds quite interesting. Just wanted to
mention the concept of storing .emacs inside a .org file in case you
aren't aware of it (you very well may be). I had a tough time finding
an official org or Worg page documenting this, but here's an example
from Sacha Chua:
- Blog about it:
http://sachachua.com/blog/2012/06/literate-programming-emacs-configuration-file/

- An example of the actual file:
http://dl.dropboxusercontent.com/u/3968124/sacha-emacs.org

I've been doing this and love it. My actual .emacs only does the following:

#+begin_src .emacs

;; set load paths
;; set load dirs and global config options
(add-to-list 'load-path "~/.elisp/org.git/lisp/")
(add-to-list 'load-path "~/.elisp/org.git/contrib/lisp/")
;; other load paths

;; setup babel languages
(org-babel-do-load-languages
 'org-babel-load-languages
 '((latex . t)
   (emacs-lisp . t)
   (org . t)
   (R . t)
   (sh . t)
   (python . t )))


;; load org-based config
(org-babel-load-file "~/org/aux/emacs-config.org")

;; stuff created by using M-x customize is at the bottom:
custom-set-variables/faces.

#+end_src

Then, in ~/org/aux/emacs-config.org, I have headlines which break down
the customization into grouped chunks. For example, a block for
org-mode shotcut options:

#+begin_src emacs-config.org

* Window options

Sets size/position of emacs when it starts...

* Org-mode options
Org-specific keyboard shorcuts

#+begin_src emacs-lisp
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-ca" 'org-agenda)
#+end_src

* Keyboard shortcuts
* Fill options
* Sunrise commander
* Misc
* Encryption

#+end_src

Obviously there's a lot more than that, but there's an example of how
one can group/arrange options by headlines so that you don't have to
search around lines and lines of nebulous code blobs to find the line
you're looking for.

Anyway, just wanted to share this in case others on the list are
unaware and would find it useful. I imagine it could even be used in
conjunction with your development as well? Both literate config files
*and* a search method that recognizes config-specific text vs. finding
every single match?
