Vinegar Cocktails

I have always considered myself daring when it comes to food as well as always trying to support innovative ideas.  So I tried to keep an open mind when reading this.  I am not sure I would go with straight vinegar, except maybe a really sweet apple cider vinegar or perhaps a rice wine vinegar that is more wine than vinegar.  But it opens up a whole avenue of potential cocktails.  I can think of putting orange bitters, a fruity vinegar, and a splash of simple syrup over ice with a wedge of lime.
