Lynn, You must join the new OASIS PKI TC that is trying to address why PKI have failed. Note: I don't share your view that TTPs are useless, as entire societies are built on "TTPs". I.e. governments. Hopefully CAs can do better than governments as the former's tasks are better defined and very limited.
Note also that FirstData's system as well as AADS have a rather limited scope with respect to transactions. For B2B-messaging in general, AADS falls short as AADS in only suitable in a bilateral relation. That does not mean that FD or AADS is wrong, it is just the universality, I claim is a bit exaggerated.
