I think that anyone with a technical background would agree that technologies like comet are useful. But it seems like yc wanted you to differentiate comet from the other approaches. How would you even make money off comet based widgets or even some kind of platform for making them? The problem is that no one wants to pay for development platforms or pre-built widgets. All of the best stuff in this category is free....django, YUI, jquery, rails, comet blah blah....
