Ah, memories of things done a decade back:

Has anything actually changed since then, Stephen?

Do any RAs actually perform effective authentication of either humans 
or corporations?  (Or, even more difficult, government agencies).

Has anyone ever implemented a private-key protection technology that 
can work in the wild, wild world of Internet-connected consumer 
devices (as distinct from tightly-controlled thin clients within 
closed networks)?

[They're serious questions, not hypotheticals, and not asked 
sarcastically.  I did a bit in this area once upon a time;  but I've 
drifted off, and Stephen hasn't, and maybe Kim too?]
