Interesting project,.

I know the person who runs the food bank\homless charity in a town near to me and this could turn out to be useful when up and running. It might be useful if everything worked in reverse too i.e. organisations in need of food can register and suppliers search for them as well.

Getting the food is another matter though - her son used to have the job of pouring bleach over the leftover bread at a local supermarket to make sure no one made use of it and they won't give away a thing. Local restaurants might be more willing to help as they might not see it as lost sales.
