I should think the PPPEXT WG would decided which guidelines, subject
to the constrains of getting documents through the IETF process :-)

I don't think it is complete but how about the following to start with:

"The PPP Encryption Control Protocol (ECP)",
               RFC 1968, June 1996.
"PPP Challenge Handshake Authentication
               Protocol (CHAP)", RFC 1994, August 1996.
"The PPP Triple-DES Encryption Protocol (3DESE)", RFC 2420, September 1998.

Unless there is significant support, I won't try to have a physical meeting.
