Yep, I do realize that and I do remember the UAC 'riots.'  But the OS 
vendor can make links that are clicked run in a sandbox and make said 
sandbox robust.  A user clicking on an e-mail link should not be able to 
pwn the system.  Period.

Most of the phishing e-mails I've sent don't have a valid reply-to, 
from, or return-path; replying to them is effectively impossible, and 
the linked/attached/inlined payload is the attack vector.
