QFT ... that's all.

And I'm not just talking about creating new ciphers. Even when I go to them with novel requirements that seem to demand some sort of new construction using existing algorithms and techniques, the very first thing they do is go to the literature to see what has been done, how long it's been in use, how widely it's been reviewed and analyzed, etc. The less knowledgeable (like me, frankly, though I'm getting better) tend to start by cooking up some new scheme. Real experts avoid that if at all possible, and if they have to do something new they look really hard at how they can prove its security by reducing it to known constructions.

I reiterate: No one who knows what they're doing creates new crypto for production work.

The vast majority of IPv6 addresses being assigned aren't routable anyway -- do you really think those random local addresses you gave on your LAN at home can be globally routed from anywhere? Sure, if you get an assignment from your ISP, but do you really want your home alarm system, clock radio and fridge globally routable in the first place?
