How much is left in the keg? This app knows.

DelawareOnline - DigitalPour, a high-tech draft management system that recently made its Delaware debut, allows beer drinkers to look up a participating bar and see in real time what beers are on tap and how much of the good stuff is left in each keg. For bar owners, it tracks just about every drop of beer sold (or lost) from their taps.
