Please explain.  I've been involved in the security area for awhile, and 
I just don't understand your point.  Isn't signed/encrypted soap 
messages over HTTP the exact same thing as SMIME over SMTP?

A recipient receiving a message with an encrypted actor and/or 
mustUnderstand cannot properly send a SOAP "actor" fault back, since 
(obviously) it doesn't know who the actor was. :)  I believe this 
impacts the processing model.
