Hey wait. I didn't even say tunnel at all ;-)

I just said you can unfortunately not claim to be an Internet ISP and
not carry the whole bloody BGP routing table by just using LISP (unfortunately).

Aka: Joe touch pointed out that something like LISP (on-demand routing information
if thats an appropriate classification in our context here) is part of overall
routing architecture (which i wholeheartedly agree), but its alas not a sufficient
option to become an Internet ISP, and so i argued its not part of the "Internet Architecture"
as it is reelevant to this doc.

Cheers
