Dear Julien, Just putting my thoughts and comments are welcome. I had an opportunity to work on providing IPv6 capability for a tape library appliance. We were unable to strongly conclude the needed IPv6 requirements for that box. The main requirement for a IPv6 node is stateless auto configuration and the optional functionalities are stateful auto configuration and gateway configuration. Based on the level of IPv6 functionality a device needs, the IPv6 requirements increase. If the device needs the IPv6 just for the point to point (master-slave) communication, then just the link local address would be sufficient and I guess the auto config of a global address is not needed.
Hence from my thoughts, the workgroup could first define the minimum and maximum IPv6 functionalities of the a constrained device. This would help device makers to classify whether the IPv6 capable device that is being developed is a constrained device or a fully capable IPv6 node, and accordingly choose the needed functionalities.
