Surprisingly, I am now able to answer my own question. It turns out that the brother of one of my co-workers performed at Princeton and she attended, not so much to hear his act as to dandle his new baby. Anyway, my informant informs me that the festival was totally awesome and magical, the main-stage doings of course but even more so the informal sessions taking place in every nook and cranny at the organisers' place, chez Jon and Rika presumably. Apparently the buzz is that the event is going to really take off next year so book your accomodations early
