>OK, yes, "retain continuity of addressability for every device" then - you'll need something at your end to push a signed notification out indicating your IP address change but there's no reason that can't be seamless like texting your contacts a new phone number but without any interaction needed. so, you mean like dynamic updates to DNS? tsig-signed nsupdate? It's old technology, and would do what you describe (well, after dns caches empty. Yes, you get to set the TTL, but even with a short ttl, I wouldn't count on a dns update percolating down in less than two hours.) Of course, there are problems with the end-to-end model you describe, where every device is publicly accessible. (Don't get me wrong, there are strong advantages to the model, too... but there are problems) I think I'd feel a little weird, a little naked without a statefull firewall in front of my consumer devices.
