+## Why We're Doing This
 The number of smart objects is going to explode, both in our homes and in public spaces. Much like the web, there is going to be a long tail of interactivity for smart objects. But the overhead of installing an app for each one just doesn’t  scale. We need a system that lets you walk up and use a device with just a tap.
