At least for example, using of send-only model for sleeping nodes to save energy. Need of eliminating the role or acting as a COAP server or Waiting for COAP observation subscriptions.

For the survey, we circulate a survey for set of questions for implementers and have some summary results collected. What kind of devices (battery, chipset, linklayer, radio, apps, transport) they are working on and protocols they are using. Sounds good ?
