Redirected Trace header draft (was Processed-By or Transmitted-By header concept)

I would like to receive comments and open discusion on the following 
document which I expect to publish as Internet Draft after the IETF 
meeting in Washington
 http://www.elan.net/~william/emailsecurity/draft-leibzon-emailredirection-traceheaders-00pre02.txt

The draft describes concept that we right now refer to as automated forwarding
by new name email "redirection" (along same lines it refers to mail systems
that do the this forwarding as "Mail Redirection Agents" aka MRA) and 
describes "Redirected:" header (which I previously was going to call 
Processed-By) for purposes of tracking when redirection takes place and  
providing information on what changes are done there to SMTP 2821 
parameters and SMTP 2822 headers during redirection process.
