See in particular the "yellow" section, which I just named for the next available nice colour my palette showed me. I hesitate to give a name to that constituency. Perhaps I have mis-represented the desires, and maybe there is yet another collection. If "yellow" would be happy with JSON format vouchers, then it would just be BRSKI over CoAP/DTLS. (The savings is only a TCP stack, and reuse of CoAP) On the other hand, I can see if you've bothered to do all of DTLS including certificate handling, then having CMS is perhaps not that big a deal, although I note that mbedtls (AFAIK) does not have CMS code. I'm interested in the part in pink, with the caveat that we need to *try* with DTLS in order to have enough data to justify OSCORE+EDHOC.
