Anything that's going to be added as metadata to the message header
needs to be carefully specified so that a client that understands the
format can reside behind a server that does not.  E.g., depending on
where this metadata is added, one option might be to require a DKIM
signature to cover it.

Consider the following off-the-cuff implementation possibility:

A header that has:

Name of server (or administrative unit (domain)) inserting the header.
What to send in report:
      ARF copy, or forward or selected header[s] or?
How to send report:
         email (including address), or some other protocol and
         destination.



I think thinking of a non-mail protocol to send abuse reports is an
excellent idea. 
Sending ARF's via email need not be the only option.  Why not use the
header 

eg X-Abuse-to: <http://mailserver.isp.com/cgi-bin/fbl>
<mailto:feedbackloop(_at_)isp(_dot_)com>
Obvioulsy the MUA must verify if the mail is authenticated , DKIM seems
a good way to do this. 

Sending abuse reports via http (POST?) should be standardized. 
If http is not available ( possibly some corporates block http access )
then you can fallback to email. 
The MUA must also have proper time outs so as to cut-off malicious fbl
urls
