I LOVE your idea. Since I live in Italy and not SF, I can't grab a coffee with you, but I will still honor your project by borrowing your idea and applying it here. (if that's ok with you)
I am going to be in SF in January (not for YC, haha) so I will contact your for an American coffee in a few months.
I'm a researcher at Lab#ID (auto-ID Laboratory) at Cattaneo University (LIUC) in Castellanza, 15km north of Milan.
If you want to grab coffee or lunch sometime I can show you around the uni.
Whenever you're in the area drop me a line: gcatalfamo (at) liuc.it
