All that left are tweaks and minor improvement. one of my faves It's perfectly appropriate to be upset. I thought of it in a slightly different way--like a space that we were exploring and, in the early days, we figured out this consistent path through the space: IP, TCP, and so on. What's been happening over the last few years is that the IETF is filling the rest of the space with every alternative approach, not necessarily any better. Every possible alternative is now being written down. And it's not useful. -- Jon Postel
