Good point. I experienced that end-users in the GnomeMeeting (H.323 client) community that never had anything to do with v6 suddenly started asking questions about how to get IPv6 connectivity because they heard that even as a normal end user you can get a /64 from tunnel brokers or your ISP (in some cases) which solves the end-to-end connectivity problem that exists with IPv4+NAT because you can get a global v6 address. IPv4+NAT problems are the most common problems in this community. 80% of all problems that people have with GnomeMeeting can be traced back to a NAT. What I'm trying to say is that there are applications that can raise a demand for IPv6 due to easier to achieve end-to-end connectivity. And Skype is not a good example for end-to-end communication "over NAT" because it wouldn't work without non-NAT-ed nodes. > How do I do the same in v4 where I want end-to-end encryption on the > application? Another good example for a field where end-users will eventually realise the use of IPv6 w/o NAT vs. IPv4 w/ NAT. The point is: there are a good number of everyday applications where end-users are painfully reminded that they live behind a NAT. And those users would definitely appreciate getting rid of IPv4+NAT if they can achieve what they want with IPv6. In this case, the adoption of IPv6 is simply a logical consequence.
