Well, I'm not sure this is what's being suggested by Jay, but many peering agreements/policies have something in them that say "prevent spoofing to best effort". Such statements could be strengthened in a global effort, and then spoofed source addresses could lead to depeering much faster/harder than what happens today. It would be reactionary rather than proactive, but still better than what we have now where spoofing is kind of like "it can't be helped".
