That is correct. When we started down this journey, we realized we could take the 'easy' approach of hardware. But with 6 billion smart phones expected in the world by 2020 each of which can broadcast and receive signal, the hardware already exists (or soon will be). The challenge of course was to do this without flashing the device, as this would completely limit growth.

One of the primary inventions is what we call 'MeshPorts' that allows the multiple apps to use the same common core on a single device. So you could have 5-10+ apps all running the same core, and thus... the data could hop between different devices even if the routing/infrastructure devices in the middle had installed apps that were not used by nodes at the start and end of the journey.
