I don't recall saying anything about the "value" of the
infrastructure. I recall distinguishing between work done in the
infrastructure, versus work done at the edges. I also recall saying
that deployment through the infrastructure usually is far more
difficult and takes far longer (to gain a level of utility) than
deployment through the edges.

interesting you express this concern. my own view is that every time
there is an attempt to get at the core criteria -- by looking at the
implications of particular proposals -- the difficult parts are
dismissed by folks.

That is because I am still trying to get folks to look at
implications, so there can be legitimate review of trade-offs.

oh? please explain.
The number of components that need to participate in an MTA
registration scheme, the administrative overhead for the operations
staff, and the fact that this is all being retro-fitted into an
existing service all point towards much, much longer deployment times.

The RMX-category of schemes call for registering authorized MTAs.

In fact, most of these do not have generalized deployment. They have
localized deployment. The password/certificate that you use for one
location is different than for another.

There are a number of ways to respond to a focus on a cost. One is to
declare the cost irrelevant. Another is to declare the focus
And, of course, another is to factor in the additional cost into the
realistic calculation of cost versus benefit.
