To supplement that, it's essentially shared responsibility. You can get federal law and state law. Under pre-emption rules in the United States, if the federal law wades into an area, it will pre-empt the state law, which, as we mentioned, is what happened when they brought in CAN-SPAM. They had a multiplicity of different standards, and CAN-SPAM was used as an attempt to try to create a uniform standard.
Subsequent to that, we've now heard a number of states say that CAN-SPAM doesn't do a good enough job. We're starting to see state-based anti-spyware legislation and even state-based anti-spam legislation that has attempted to address what they saw as holes within CAN-SPAM. Sometimes there's been litigation as to whether or not it is a valid state law in light of the fact that there is a federal statute with CAN-SPAM. Thankfully, we don't have to deal with quite that complexity.
