Yes, that's one failure mode.  E-mail clients that hide real addresses 
make this even worse.

All this talk has given me some really good insights for framing the 
problem -  "what are you trying to secure, who are you securing 
against, what are the failure modes," etc, then I thought to myself, 
"this is probably one of those 23 problems that was solved shortly 
after RSA published their paper" and is continuously re-invented.

Google is showing me that this _is_ continuously re-invented; does 
anybody know if there's a gold-standard?
