[OpenID] [security] Another Client-side Password Phishing Mitigation Idea

Hi All,

Read my proposals from about 3 months back.  I explained how plugins
will need to recognize OpenID login pages.  I proposed the technical
solution. It's the same concept as "IdP initiated logins" (since
something else besides the RP web page initiates the login - eg - the
browser plugin). 

Be warned - my proposal got flamed and ignored.

A few times subsequent to my proposal, I requested someone correlate
all the proposals - again - this hasn't happened, so now we find
ourselves back in a loop discussing the same things again.

IMHO - OpenID needs to have hooks to let anti-phishing technology
evolve, otherwise both will die off (succumbing to InfoCard)

Kind Regards,
Chris Drake,
