er, read the text that I was responding to.

the user does not want to be reached -- end of connection

Easy in pull model to store a URL for the site so that when the data  
changes, the user's software agent can ask the the user if they want  
to give it to the site.
Data only moves when it changes, and the user is involved in it being  
released all the time.

they still are storing the URI to get the data and the credentials to  
retrieve it, so little difference if they are compromised. They  
either get the data, or get how to get the data

To rise up a level, why are you being so abrasive?
