good thing i disable IPv6 at home because it's an annoying pita and i run no machines with windows in the cloud, checkmate :P
on a more serious note though I don't think machines with ipv6 enabled that are behind a NAT are likely to be vulnerable to this, i suppose maybe wormable if you can natpunch through some p2p voip or gaming service, it's the sort of patch i would probably install if i were made aware of it (if i had ipv6 enabled), but being made aware of it doesn't like, leave me worried, and i don't consider it to be likely to affect me unpatched
NAT and IPv6......you really should educate yourself about it IPv6 is not "that" new...trust me (bro). You know, keep learning is a big part of life ;)
