I believe the whole point of the article is to find a successor to BGP. BGP has been around a while now and has scaled to this point. However moving forward I don't believe BGP is the way to go. I don't think BGP can scale to the degree the IRTF needs for developing countries. With most large organizations doing multi-homing with different service providers scalability is not the only issue. There is currently no way to load balance across different service providers without using an additional appliance. If the IRTF could develop a protocol that will scale, load balance, and converge quickly when a network event occurs they might find the "silver bullet" they are looking for.
