State versus stateless, intelligence in network versus intelligence in hosts. - Layerists: network-layer vs some upper-layer - Tussle-field side: Vendor, End-user, Service-provider or Content monopolist - Open source vs proprietary code - Software vs hardware - Router, end-host, content or applications - Language C, LISP or some other obscure language that must be protected - Purist vs middlebox NATter - Tourist vs Retired - Corporate drone vs Volunteer for a better world - NSA operative vs … I have never worked in an organisation more diverse than the IETF. Is it perfect, and does so much diversity make reaching consensus easy? No, but I think we should be darn proud of ourselves. Ole
