Thanks for voicing these concerns, Richard. We do need to make practical progress on this front, however. 
Could you suggest an alternative technology to OpenID that has some level of public currency as a standard 
and implementation? You mention that OpenID has "very little industry uptake" but as far as I am aware, any 
alternatives have even less. OpenID has at least been taken up by the likes of Google, Yahoo, Paypal, and 
the BBC. Also, I'd be grateful if you could provide some links to analysis of the security deficiencies of 
OpenID so that we can understand them better, and also, which we could perhaps use to base any evaluation of 
a replacement standard.

Many thanks,
