Any hope/plugin for vi/vim keybindings?

Hi all,
let me say you're doing a very great job.
I think I can put myself in the group of old-xcode users and I'm mainly a C++ / Objective-C developer so I've never been a user of Java-focused IDEs, but the different look doesn't really scare me.
I'm quite happy with newest Xcode4, even though indexing/refactoring leaves a lot to desire, but there's one thing I can't really live without and it is a vi/vim input mode.

I spend most of my time working on unix based machines, counting MacOSX ones in them, and my preferred editor is Vim, I've already asked this same question at the early stage of Xcode developer previews on the apple forum, but the answer was mainly: NOPE.

So, let me try again: is there any hope to be able to use your IDE with an editor configuration/plugin that allows me to stop writing lots of "jjj" "kkk" "cw" etc... (who knows Vim knows what I mean).

I repeat, I'm not familiar with this line of IDEs, so maybe there's already a plugin (I rarely use Netbeans for C++ and it has one for example) for that and this question is just a bit silly?

Thanks,

Andrea.
