Sounds like you already found my vim feed, but yeah, it's at http://gfxmonk.net/dist/0install/vim-custom.xml (it's not on that index page, because nobody else is likely to want it).

I've contributed to both the python & ocaml versions (and I made the logo :)). The ocaml version has not existed for all that long, I've only sent a few patches - I believe the porting itself was entirely done by Thomas, who's done great work.
