   I'm a strong advocate of DNSSEC, but I'm certain it will fail users are
required to notice an indictor of its presence or absence.  SSL indicators
are visible to end users and users don't notice them.

   I have been working on a new standard that would employ DNSSEC to reduce,
rather than increase, the amount of security information that users need to
be made aware of.  The standard removes the need for users to pay attention
to the browser padlock icon and other HTTPS indicators.  When I've talked to
folks at Mozilla and on Microsoft's IE team, I've found the generally agree
that this is the area where DNSSEC can provide value to them.  Alas, because
it introduces a new record into the DNS, it is out of scope for this working

   When it comes to security indicators, more is not necessarily better.
