We may not. However, without ULA, I question whether people will bother 
adopting IPv6 at all. If that's what the community desires, then so be it. 
However, I expect market forces will drive the requirement for ULA. If it's 
missing, I expect a repeat of another happening with IPv4, that being 
people picking random address blocks to use.

As for the ingress filtering issue, education and contract terms are two 
good answers. I'd like to see network operators considering ingress as part 
of their aggregation router buying decisions, of course.
