IPv6 doesn't fundamentally offer end users anything far beyond the current standards.
I'm imagining a protocol for less tightly coupled endpoints could be written to, while the "switches" merely translate traffic to route it on current infrastructure. A more application agnostic version of mixmaster or TOR, so to speak. The important part, is really to get enough of a variety of end user apps written to it, to prevent anyone from knowing much about the traffic simply due to the protocol spoken. Then, over time, to optimize away more and more crud, until we've got dedicated hardware. It may still be a bit utopian, but the current mess isn't really serving people all that well anymore, either.
