I have wondered more than a few times, what it would take to port org-mode to Vim ...

I note that someone gave up on the slime port of vim for various reasons ...

AFAIK Slimv is being actively developed and quite usable (although I haven't used it myself): http://www.vim.org/scripts/script.php?script_id=2531

Also wrt org-mode: if one called out to Emacs from Vim for exporting to different formats it shouldn't be too much work.
