This is for embedded Linux devices with a set of proprietary applications (small volume commercial/industrial control, no consumer device). Mostly non networked, so we have to distribute application updates via USB (in the networked case, we a use VPNs separated by customer groups to deliver updates, so this layer provides the encryption without requiring the update archive to be encrypted).
