My take from this whole discussion is that PKI has been sold to unilaterally to one group of people. It has been sold to large banks and security heavy industries. They tend to make things more complicated, and their security people are too security conscious, having to deal with the most determined enemies. A good security profession in banks MUST like a good military man, be far from the daily family life. He is there to think about disasters, so that they don't happen, so that nobody should think about them. 

What should happen instead is to lower the security requirements, and enter the mass market. Just as we don't put fort knox security on our houses, but use simple keys with well known security issues, so one should start using PKI in a cheap but useful way. Of course PKI has to solve a problem that passwords don't solve, otherwise they can't get traction. But they don't have to solve EVERY security problem. 

To get that ball rolling PKI has to be dirt cheap, and extremely useful. It has to be 
- one click to create a throw away certificate
- authenticate across all sites (as Facebook connect does)
(-> tie into the social web)

That would provide a big enough improvement over passwords to get people interested, and it has a viral side to it. As soon as it works for enough people, those people become interested in getting others on board too.

With millions or billions of adopters you can create the momentum, and the mass market, that will make all the other problems easy to solve. If there were just a million active developers in open source software using PKI every day for checking in software and communicating with their peers, you would soon find the technology make its way into every web site, and browsers being adapted to make their interface easy to use. With mass adoption it would be much easier to solve all the other technological problems, because citizens and politicians would have an immediate understanding of what you were talking about. 

That is what http://webid.info/ offers. Start with the low hanging problems: passwords. Then move on to add technology piece by piece to move up the security ladder.  This is the way technology works. Microsoft started with DOS and moved its way up to more and more secure versions of Windows - whatever you think of their OS you can't deny that that was a very successful strategy.
