Steve,
it appears that everyone wants to write the follow-up.
If Matt is up-to-date on the current status of ICA/PCA
developments, it seems plain that he ought to update
his own article! Of course, he can share the draft
with PEM-DEV if he wants to get input (no fear there
will be a lack of it!!!).
Internet Society is prepared to receive proposals to
operate Policy Certificate Authorities - there is,
however, no detailed specification for what should
go into it yet. I guess we will have to approach
this on the presumption that the effort will have
a rather fluid character until all of us have
some experience with what is needed. I am depending
on Jeff Schiller's good graces at MIT for development
of some software to help manage the PCA "conflicting-
assignment detection" database to help PCAs from
assigning conflicting Distinguished Names (it won't
be perfect since some applicants for certificates
will have gotten their Distinguished Names from
places which are not performing such conflict
resolution, but it will help).
