Richard,
  I read the draft and I like it.  More comments inline.

I think "the problem" can be solved with existing mechanisms, but I like
your proposal.

One way to do it is switch the port to an internal "test" port.  Is this
what you mean by "build test circuits"?

I highly doubt it, but I'll let them add their input.

Thanks,
Jonathan

To remove yourself from the IETF Announcement list, send a message to 
ietf-announce-request with the word unsubscribe in the body of the
message.

Internet-Drafts are also available by anonymous FTP. Login with the
username "anonymous" and a password of your e-mail address. After
logging in, type "cd internet-drafts" and then
        "get draft-rbradfor-ccamp-lmp-lol-01.txt".

A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html 
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt


Internet-Drafts can also be obtained by e-mail.

Send a message to:
        mailserv@ietf.org.
In the body type:
        "FILE /internet-drafts/draft-rbradfor-ccamp-lmp-lol-01.txt".
        
NOTE:   The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility.  To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command.  To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader.  Different MIME-compliant mail
readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.
                
                
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
