I thought your main complaint with OpenID is that the user could be
coming from an untrustworthy provider such as
http://www.jkg.in/openid/ , so OpenID provides no guarantee that a
user wasn't a spammer. Do you also believe that this makes OpenID
inappropriate for its Single Sign On roles, as seen with
http://www.highrisehq.com/ , http://www.basecamphq.com/   ,
http://ma.gnolia.com/ and many others?
