Hi Hannes, So yes I agree, minimal ESP better fits lwig whereas diet-esp better fits ipsecme.
Orange already operates networks of smart communicating objects, either directly or through its joint-venture m2o City. Orange is committed to contributing to the advent of the Internet of Things. Dominique is maybe the best entry point to know more on our activities with IoT. We are currently looking at using IPsec and compare it with TLS as a research topic. Currently Tobi implemented Diet-ESP on Python and for contiki. As soon as we have published tests we will provide the code as opensource.
