The CS10 has Bluetooth and wifi and allows connection with the Service Tool by a device that is connected to the CS10's Bluetooth or wifi network. The CS10 can have its own SSID or connect to another network which are both nice options. If the CS10 is connected to your company network wifi and you connect to your company network over the internet via a VPN then you would basically be connecting to the ServiceTool via the internet. I don't see any other way that it could be achieved.
FStelzer, did you hear that during the CAB, or are you thinking of maybe the CS100?
