[JM]  Robert - are you are saying you do not support the draft as I can
use hacks/workarounds such as allow-as-in or as-override in conjunction
with site of origin to add loop detection or am I misunderstanding your
suggestion?  What if I want to use BGP as designed for AS_PATH loop
detection and be able to do standard troubleshooting/filtering based on
AS_PATH and not worry about (mis-)configuration of soo?   Why not have a
range of private ASNs large enough to support internal networking
requirements of organizations w/o the use of more and more features?
