You appear to keep, in your thinking, equating NPTv6 with NAT44. They are actually different, and have different effects. There is no reason whatsoever that an IPv6 host behind an NPTv6 translator can't offer services. To offer a service, with or without NPTv6, it will have to keep DNS (and any other name service it is using) informed of its current address. In the case that NPTv6 is in use, that service will have to be a little smarter, interpolating from that what other addresses might be relevant.
Actually, from a IUse point of view the NPTv6 will only be an IPv6 oriented MAP-NPT function (Multi-Adressing-Plan Network Prefix Translator). What is of interest to the user is IDv6 (or any large enough sub-addressing system) that can be prefixed (what ever the prefix) to be routed to the other end in order to be intelligibly used on the other fringe. There can be many additional fringe to fringe services and even IDv6 massaging. Depending on the GRIDv6 (Global Region IDv6, i.e. belonging to standardized sub-addressing plans).
