No, the conclusion is that for IPv6 there should be something that behaves 
much like current IPv4 NAT boxes, ie do stateful firewalling and only let 
internal computers initiate conenctions outgoing, do protocol sniffing for 
allowing incoming new connections, and use some uPNP like method to do 
temporary firewall openings.

This is the social contract of the current home gateway ecosystem, and 
intiially IPv6 devices need to replicate this.

Last I checked, this was the conclusion of multiple IPv6 related 
IETF working groups, check out "homegate" and "v6ops" WGs for instance.
