I am not totally familiar with International Law, but the recent move by Microsoft to offshore some customer's data to avoid NSA surveillance seems a bit silly.
So we might eventually need a passport for data so that we can check the country of origin as it passes through our domestic routers, gateways, and firewalls. Maybe there's even a place for the TSA in the equation. We'll set-up data checkpoints and have TSA agents determine its origin, or prevent its entry into the US

Yes, this sounds silly, but the notion that data can be constrained by an international borders is quite a feat for the World Wide Web itself.
But when you think about all the nefarious and suspicious activity coming from Western European and Russian sites, it might not be a bad idea.
