        The problem is there is no perfect solution to these challenges
that the industry faces.

        The enhanced SSL certs and browser magic, eg:
www.paypal.com w/ Firefox3 gives a nice green "happy" bar.

        If you don't invest in these, or if there is a lack of user
education around these issues it's just one big Pharming pool.

        I talked to some govvies today and made what I believe is
the clear case when it comes to "Doing the right thing(tm)".  My
case was that the industry would do the right thing as a whole.
There would be stragglers, but the risk of doing nothing is too
high.

        If your nameservers have not been upgraded or you did
not enable the proper flags, eg: dnssec-enable and/or dnssec-validation
as applicable, I hope you will take another look.
