I don't see a "killer IPv6-based business app" as likely, but IPv6
does seem like a good way to solve some of the problems that NATs
cause for communications between private v4 networks. It won't be
a single app that causes businesses to shift, it will be the ability
to run whatever protocols the businesses want to use to talk to each other.
Hold on just a minute. Business applications are moving away
from limited client/server models towards synchronous or asynchronous
exchanges between systems that are sometimes clients and sometimes
servers. I don't want to rant at length here, but peer-to-peer business
apps are absolutely what we need for IPv6.
I think we're in strong agreement. I was only pointing out that the
incentive for businesses to move to IPv6 might not be one or two well-known
apps that everybody uses, but a more general need to use peer-to-peer
communications between businesses.
