What has kept SCTP down is the fact that the NAT code would have to be modified to support SCTP connections because they can be multi-homed. That will never happen. So, ironically, once the majority of the world has transitioned to IPv6, SCTP should be theoretically usable to talk to anyone if you're both not behind NAT anymore.

Yeah, but the cheap consumer routers that do not let SCTP through the NAT do not generally let IPv6 through either.
