I read it really often, as I'm involved in X.509 PKI since 1998,
working for a large PKI operator, starting by being an SET CA operator
for 8 banks and 3 brands. We host dozens of CAs on our facility; we
deploy new ones everywhere in the world, auditing people, writing
CP/CPS; we produced tens of millions of certificates; we produce
millions of OCSP replies every day, and a lot of other services around
I know X.509, and I know RFC2246/4346/5246, among others.
Go tell Apache, Sun, Mozilla, Opera, Microsoft, and a bunch of other
vendors that isolation of CAs is irrelevant, and come here after.
