CHR as a VPN concentrator.
Remote ROS devices are connected to CHR over VPN.
Remote VPN traffic is forced to self register and pay to gain Internet access using Hotspot/Userman on CHR.
How exactly would one setup the CHR Hotspot Interface to accomplish that?
I'm open to ideas. In this scenario I want to authorize all traffic from the remote ROS once they have paid for service. I assume this would be easier to accomplish on the CHR as it will only see the remote ROS device as a single IP.
