Hi Michael, Thanks for writing draft-richardson-in-memorium-00 [1]. I like what you wrote in Section 3 (privacy considerations).RFC 6890 states that the IETF occasionally reserves an address block for a special purpose in order to support new protocols or practices. I'll leave it to other people to discuss whether the requests in Section 5 fit within protocols or practices.
