Re: IPv6-only devices?
I can see also one case that can perfectly match most of this examples, never mind is more a "business" or "marketing" one:
- A team of a hardware vendor+service provider that want to create a exclusive "product/service/application", only v6, because they
only want to sell it in the provider network (as a value added service to attract new customers).
It could be the same for a new application, instead a "hardware product". The service could be installed in a standard PC
(requirement: OS IPv6 enabled), but will use only the IPv6 stack.
