Hello Al: To be clear, I agree with Serge's second statement again and I want to restate that the value I see is that it provides a "nice" secondary data point as to the site being referenced. either in the Link Rel, header, and/or P3P file. The more information available to detect phishing the better. I think the statement again that we support w3c technologies is great and whether tool makers wish to implement P3P is another thing. I think the value is machine readable validation and I think it is a "Nice to have" 
 
Cheers!

I agree. I have worked with P3P. There are 2 major problems wrt adapting it to our work

1. P3P involves writing a policy wrt what info you are collecting, what you are using the info for, who you are sharing this info with and what they are using it for. This is not about security and would have to be subtantially expanded. A website could be collecting and safeguarding info securely and using it in a manner that violates a users privacy concerns. Conversely, a website could be respecting a users privacy concerns but not securely collecting and storing the info

2. Privacy is about intentions and depending upon how much you trust the web service provider is how much you believe the websites assertions regarding their handling of sensitive personal info. Security should be more measurable and not relliant on a website declaring that it is secure

The problem with doing anything with P3P in this context is that the
website sets their own policy.  Thus, if we make some "secure" indicator
in browser chrome, we're now allowing the website to modify this trusted
indicator, which we already agreed is a bad way to go.

"Machine Readable" is also huge the P3P file (or server headers) could be used to validate site information for security context as well. Being machine readable it would yet be another way to validate other security context. However - this again is a matter of how do we validate compliance or even if we want to be in that business.

It is 2007 :)  This includes the note, recommendations, downloads, supporting information and presentations. Any company providing a user agent should provide an accessible solution. Following Canada and the EU logic: It is a human rights issue versus just a technology issue. Canada sees CLF as a Human Rights response addressing Accessibility, Languages and more. A good example would be the question of colour. Colour Specific could be Colour + Value specific and have alternatives.
