Vi for Mac OS X eveverywhere!

So cruising freshmeat today, I came across the world's niftiest Input Manager, http://www.corsofamily.net/jcorso/vi/. It lets you use vi command mode commands anywhere that uses Mac OS X's text input doohicky, which is pretty much everywhere. TextEdit, Safari, etc. all now have Vi key-bindings. It's not perfect, every time I've tried to edit something in this window for instance, I haven't been able to see the cursor, but it does work admirably in TextEdit and Colloquy, which is good enough for me. Hopefully it will get better.
