[Jay Carlson just posted that in > response to another discussion] That original, somewhat-square, wheel was refined over many millennia so that it is round and rolls smoothly, is very widely deployed, and various versions of it are widely available and interoperable from many sources. There are many studies and examples that new, whiz-band technologies to replace it don't go anywhere. Instead, when major new developments/improvements come along (think, e.g., pneumatic tires), they get retrofitted onto more or less the same old wheel rather than replacing it. If SMTP is irrelevant to your plans except insofar as you think your ideas will cause it to be less {useful | accepted | relevant} then let's stop talking about it and instead, concentrate on the problems you are trying to solve and how you determine success... as Christopher and others (including myself) keep suggesting. I would personally predict that, like that historical wheel, the wide deployment and use of SMTP would make it much harder to displace than you seem to be assuming -- a prediction that seems to be reinforced by the large number of "better than SMTP" that have fallen by the wayside. But, if you disagree or don't care, go for it and let's move on. Very similar comments apply to trying to break or supercede an ICANN-controlled DNS and the consequences of the name-renting behavior that it has enabled and encouraged. If you see that as a goal, then we need to understand and perspective and why it is relevant to your success with the Mesh. If it would be just a desirable side-effect when you succeed, then let's move on. best, john
