With respect, you're flat-out wrong in this context. For the community
having this discussion, *the* important issue is stopping spam, which
tops all surveys as the scourge of the Internet age.
We often set out to solve one particular problem, but doing this
properly implicitly means not replacing it with another problem. If
you propose a solution that free software operating systems are not
allowed to use, the price of using that solution would be our freedom.
Some will choose your solution and give up their freedom; some of us
will uphold our freedom and not support the solution.
The issues you raise are serious ones, and I respect their importance.
But they are only *slightly* more relevant to this mailing list than
the relative merits of Levitra and Viagra as spam-enabling
technologies.
The question is whether your solution to one problem brings with it
another problem. You have no control over Levitra and Viagra, but
you do have an important say in this.
Thanks in
part to that history, I am confident that the IESG and IAB will not
permit the emergence of a standard that excludes *anyone* from "full
participation in email."
I hope you are right.
