Hi Woj, One thing about your propsed wording is that it reads like addressing independence and state reduction can be realised concurrently. What about the following (with some other slight language cleanups):
Lightweight 4over6 is a solution designed specifically for complete independence between IPv6 subnet prefix and IPv4 address with or without IPv4 address sharing. This is accomplished by maintaining state for each softwire (per-subscriber state) in the central lwAFTR and a hub-and-spoke forwarding architecture. [I-D.ietf-softwire-map] can offer these capabilities or, alternatively, reduce the amount of centralised state using algorithmic address mappings rules, introducing a relationship between the IPv6 subnet prefix and IPv4 address. This relationship also allows the option of direct, meshed connectivity between users.

It doesn't use a mapping algorithm to map between IPv4 and IPv6 addresses, which was the point that Qi expressed in the text he sent out this morning. Text I (re)proposed said it all: Lightweight 4over6 is a solution designed specifically for complete independence between IPv6 subnet prefix and IPv4 address with or without IPv4 address sharing.This is accomplished by maintaining state for each softwire (per-subscriber state) in the lwAFTR and a hub-and-spoke forwarding architecture. [I-D.ietf-softwire-map] offers the same capabilities along with means for reducing the amount of such state using *algorithmic* address mapping rules, which however introduce a relation between the IPv6 subnet prefix and IPv4 address. This relation also allows optional meshed connectivity between users.
