I love this concept, and the general potential of the sharing economy to minimize waste though. I'm curious, what are the legal barriers to sharing food that you have come across or anticipate? Perhaps it's different, but with prepared food, I've read about a lot of challenges starting up because of all the liability issues. I've heard of www.leftoverswap.com, www.shareyourmeals.net, www.feedingforward.com. There's also a SF-based nonprofit called FoodRunners that does donations and claims to be protected under a Good Samaritan clause, but I know that when I asked my old company if it was OK (i.e., sufficient legally to make them feel comfortable donating the tons of corporate lunches leftover), they couldn't actually find this clause. In any case, I'm fully supportive because I believe incidents that do happen will be few and far in between and people are rarely intentional, but just wondering how hard this will be to enact.
