Several years ago I would have said no, but now I think
it's neutral, to be honest. A lot of crud that's popping
up in the network is the inevitable result of privatization -
you can't change the economic incentives and assume that
everything else will remain static. A model based on selling-
you-a-service is a model that assumes that, among a host of
other things, the edge of the network is visible. It
probably doesn't *need* to assume that, but until someone
comes up with an end-to-end business model, the end-to-end
networking model is going to remain under assault. And that
implies that technologies, like integrity protection, that
rely on end-to-end transparency will continue to have problems.
I don't see how you can fix the technology without fixing
the business model.
