Now it's time to wait to see what the legal response is. I am sure the EFF and ACLU are more than a little upset about officially-sanctioned censorship. I am sure the courts are interested in determining whether or not domain names are property that can be seized by Customs.

(It would be especially interesting to see what would happen if the DNS server would only service requests from areas in the US that are more than 200 miles away from the border; territory that ICE admits they have no jurisdiction over.)
