> IPv6 is already being deployed from top tier mobile carriers and that allows globally rout-able addresses even behind NATs.
With all due respect, if your solution depends on the following developments in the real-world:
(1) Everyone upgrades their cheap DSL/cable home modems to something that supports IPv6
(2) Cell carriers allow incoming mobile data connections (can you say mobile DoS?)
(3) People modify their firewalls (again, nothing to do with IPv4 or IPv6) to allow incoming connections
(4) You devise some way of allowing static or otherwise identifiable IPv6 IPs, even when the ISP doesn't give you a static IPv6 IP
then I would say you have a number of challenges ahead of you. Assuming that device X and connect to device Y on the Internet, for consumer devices, is a very difficult proposition.
