Hi Jason,
nice idea; I'd definitely prefer the 2. though, i.e. let the Elisp speak
for itself. Furthermore, contents of the Viper init file, which is
different from .emacs/init.el is relevant, too. Also, why didn't *you*
paste your customisations here to begin with?

I have no .emacs; I use init.el which loads some other init files. Here
are the Viper/Vimpulse-related parts with some explanations:

init.el:
--------
(setq viper-custom-file-name "~/.emacs.d/init/viper")
(load "~/.emacs.d/init/init-vimpulse.el")

;; Don't mess with my minibuffer, bad, bad Viper!
(remove-hook 'minibuffer-setup-hook 'viper-minibuffer-setup-sentinel)

;; Don't mess with my Esc key in Vi state, bad, bad Viper!
(define-key viper-vi-intercept-map viper-ESC-key nil) ; viper-intercept-ESC-key

;; Don't mess with my input methods, bad, bad Viper!
(defalias 'viper-set-input-method 'ignore)
(ad-deactivate 'activate-input-method)
(ad-deactivate 'inactivate-input-method)
(ad-deactivate 'toggle-input-method)

init-vimpulse.el:
-----------------

HOWGH. Looking forward to seeing yours!
