What I am certain of is that our ability to evaluate the subtle differences between these proposals, and the advantages and disadvantages of each, is compromised by a widespread failure to respect the diversity of experiences and the diversity of users' legitimate needs. Under such circumstances, people are forced to shoot down half-baked ideas, just as a means of damage control, rather than trying to refine them. As a result, I don't think any of the various proposals for unique non-PA addresses have received adequate scrutiny. > > > Our task is to look at the overall system the way that network > > > managers really run (or want to run) it, then figure out > > > what it will take to make that happen. > > > > funny, I thought our primary task was to design a network that could > > support useful applications. > > No that is the network managers task.

If the protocols we design don't support what users need from the Internet, there's nothing a network manager can do to fix this. Keith
