From the New York Times: In India, Grandma Cooks, They Deliver.

To achieve [home-cooked meals delivered to workplaces] in this sprawling urban amalgamation of an estimated 25 million people, where long commutes by train and bus are routine, Mumbai residents rely on an intricately organized, labor-intensive operation that puts some automated high-tech systems to shame. It manages to deliver tens of thousands of meals to workplaces all over the city with near-clockwork precision.

Cool. I am all about highly efficient informal networks.
