I couldn't touch type and really couldn't force myself not to look, so I bought a Das Keyboard and threw out my old keyboard. It was rough at first, but I doubt I could have learned faster any other way and as a bonus I ended up realizing the joy of typing on a mechanical keyboard.
I've met programmers that don't touch type, but I've never met a PC gamer that doesn't.
And yes, your idea would be awesome. That would actually be a sick WoW add-on. I doubt you can pull different localizations through the API though.
