Hi. Indeed, iCloud syncing will be awesome. I did not add it to this release yet though. If anyone wants to contribute, patches are welcome!

No kidding? If I just edit $HOME/.vimrc, it will start syncing? Or do I need to do something special?

If it can sync .vimrc, could it also sync a directory over iCloud? That would be amazing. I'm a die-hard Emacs user, but this would be enough for me to use Vim for at least some work.
