Google goes Premium?

Beta News reports that Google is testing a new service that would allow publishers of all kinds with restricted content (stuff you gotta pay for) to still have Google index their material.  Such results would display in the regular Google results list "in a special content area on the  right side of Google's search results underneat the AdSense advertising links."  Users could preview the result for free, but would have to pay per the publisher's regulations.  Gary Price discusses the project more on Search Engine Watch.
