Love it, awesome execution! I might cross-post this on the Leaf forum, since you are using an upgraded Panasonic trickle cord.
For what it's worth, we had trouble getting a permit for installing a public charging station in front of our house and briefly considered concealing a 240V plug in a hitching post instead. We live in the old quad of a California Mission city and hitching posts are still in our municipal code. The setup would have been similar to yours; I'm really impressed by the attention to detail.
