As someone who's moving towards integrating OpenID (RP and OP) into his
employer's web apps, I would very much appreciate URLs to such critiques. 

>From what I see, the most glaring problem is that some "major sites" that
act as OPs (Flickr, AOL, etc.) still do not have https:// identity URLs, so
RPs cannot leverage cheap, ubiqitous SSL/TLS PKI to help thwart the more
obvious DNS and MITM/phishing attacks. 

BTW, whoever maintains http://openid.net/get/ should probably change the
Yahoo information to "https://me.yahoo.com/" since that works and, unlike
http://openid.yahoo.com/, uses SSL/TLS.

Thanks,

Peter
