The national air traffic system makes a poor analogy to the Internet in this case, IMHO. If O'Hare got nuked tomorrow, we'd have some serious disruption in passenger traffic. If PAIX fell into the ocean, OTOH, traffic would simply route around it. Isn't that how we try to engineer the Internet? So in other words, yes, everything is important, and yes, nothing is particularly important. Grant -- Grant A.
