Governments typically already do this for classified information. If there's data that really shouldn't get out to the Internet, don't let anything on that network connect to the Internet. They'll also have procedures for moving things from one network to the another which are intended to avoid inadvertent disclosure and malware infection. Your average company or public radio station won't implement this sort of thing because it's too complicated and costly--or at least that's been the attitude until recently. Maybe we'll start to see the use of small isolated networks for things like the security system they mentioned in the article, or accounting/HR which deal with PII and money. Then you just have to convince the security guy not to plug his personal laptop into the security network, and get the HR employees to stop moving USB sticks back and forth between HR-net and the regular Internet-connected LAN :)
