This is clearly controversial, but maybe worth thinking about.
Many years ago, when working with some fax-related technology, a customer
mentioned to me that a big advantage of fax vis-a-vis email was that it was
_not_ free to the sender.
If we were to take a view that email should not be free for anyone to send
to anyone, then I think that would fundamentally constrain the technical
design of any system that conforms to such a goal. Is freedom to speak,
for free, at anyone truly a desirable goal in a global network?
The details of what is or is not free can surely range over many
variations, but my question is directed to the principle, not the detail.
