But all of those are extensions and (historically incremental) improvements on the original design, not "toss the original design principles of the wheel and replace it with a completely new model". Depending on how far one wants to push the analogy, the idea of a suspension system might be an exception to that but suspension systems did not replace the idea of using wheels without them, only solved some specific problems for some specific types of applications. But, again, I think we are going around in circles. Other than acting as a two dimensional prototype or representation for said wheel, this doesn't appear to be about SMTP (with or without encryption) except for an (IMO extravagant and unrealistic) claim that the proposed new system will supplant it. Can we get to clear statements about what specific problems are being solved, how the proposed mechanisms will solve them, and what their scope/ applicability are? best, john
