Software turns iPad into a beer keg control center

I guess Yelp has some kind of Googlesque 20% time thing, because engineers at the company found the time to create something called the KegMate.

The software enables an iPad, attached to a keg of beer, to keep track of who's drinking and how much (using RFID scans no less!). It displays the temperature of the beer. Users can rate beer quality, and see who else has been drinking.
