grub points to this TechWeb story about a software tool (NetRecall) from a company called Athentica which they claim can selectively allow viewing, copying, and forwarding of online materials. The idea is to maintain control of content on a per-person or per-category basis -- something which could have good or bad applications, but which sounds difficult to implement effectively no matter what use it's put to. (Will the required plug-on also block all screenshot utilities? If not, exactly who is it intended to stop?) Of course, since circumventing even simple methods used to "protect" copyrighted materials is illegal under the DMCA, perhaps that doesn't much matter.
