IPv6 anyone? People must start to understand that "Because this is the way it is" is a valid, actually extremely valid, answer to any question like "Why don't we just switch technology A with technology B?"

Despite all the shortcomings of the old technology, and the advantages of the new one, inertia _is_ a factor, and you must accept that most users will simply even refuse to acknowledge the problem you want to describe.

For you your solution to get any traction, it must deliver value right now, in the current ecosystem. Otherwise, it's doomed to fail by being ignored over and over.

Also there needs to be a big push to educate people on <new thing>. I know TCP very well, it would need quite a lot of incentive for me to drop that for something I don't yet understand as well. TCP was highly beneficial which is why we all adopted it in the first place, whatever is to replace it needs to be at least that beneficial...which will be a tall order.
