 I have studied this paper. Your are mis-interpreting here. The RPI
paper is an increment to OSPF or BGP for some traffic engineering
functionalties. It doesnt require signaling whereas, diffrout=20
requires signaling. Also, we are taking more from a diffserv=20
point of view.
 As i told, routing in peer to peer networks and some overlay=20
systems can use diffrout concept. We can explore certain non-
cooperative algorithms for an alternative to SPF. But as mentioned
before, this will not work out if we see from an engineering=20
perspective.=20
