That is a very interesting desideratum.  It requires an "append-only"  
property that we've talked about but haven't implemented, and I think  
it requires public key encryption.  Would you please open a ticket  
saying you want this?  (The contents of your message to the list  
would be fine as the initial comment in the ticket.)
