Stephen,

I agree wholeheartedly.

The SACRED group have invested a lot of time chasing a new strong-pw authentication
option (PDM) that was being pushed actively by it's proponents.  More recently it
has been suggested we should take on a much larger technical issue -- namely that
http is not suitable for the transfer of SACRED authentication protocols and
credential data.  I'd suggest there are oceans of empirical data that indicate this
conclusion is highly debateable.

Keith Moore, among others, has clearly articulated http-specific technical issues
that should be dealt with by those who would like to create a http-SACRED binding.

Others may want to create a BEEP-SACRED binding or a TCP-SACRED binding.

In "Blown to Bits", Evans and Wurster have said:

"However the shift in standards is not just from proprietary to open.  The Internet,
extranets, and intranets are all variants of the same thing.  They use a set of
lowest common denominator standards.  These trimph because of the principle of good
enough:  at some point in the advance of technology, generic standards become good
enough for their advantages in universal acceptance to outweigh their disadvantages
in any specific application."

I'd suggest "universal acceptance" is an important dynamic specifically with respect
to what SACRED is trying to do.
I also suggest that http, BEEP, TCP can all be made to work well for this very
simple task.
