Really, it's a technological progression. The reality that exists right now is that we need an application programming interface so the public health authorities can develop the apps that allow them to build that relationship with the user and request that they allow tracking through Bluetooth.
As a second phase, we're pushing out modifications and improvements to the operating systems on the device itself, so that much of that work is being conducted through the operating system. It's a technological improvement rather than an expansion of the program or its capacities.
