Having built dozens of (private) PKIs over the last 12 years, I do
have some ideas on addressing the weaknesses.
Rather than shoot from the hip, the logical way to propose a solution
would be to write a paper on it and submit it to IDTrust 2012 for
discussion. If it is selected, it will have the merit of having been
reviewed and deemed worthy of discussion. If not, I will have wasted
only a few reviewers' time.
P.S. IDTrust 2012 is likely to be announced here sometime in the next
few weeks: http://middleware.internet2.edu/idtrust/
