Thanks for the (detailed) exposition; this I can work with. :)
I've added a /rough/ sketch in commit [70e470f6fe], which utilizes
both the global mark ring and the ordinary, buffer-local one.
It's not bound by default, so add

    (define-key viper-vi-basic-map "\C-o" 'vimpulse-jump-backward-globally)

to .emacs or some such to test it.

Although, when I come to think of it, wouldn't a separate Git branch
be better for testy things?
