Will search become exclusive?

Reading Eric Schmidt’s comment about Google’s plans to index Orkut data, I wonder if we’re heading for a time when search engine companies will try to develop a competitive edge–not to mention make more money from highly targeted paid search results–by laying exclusive claims to particular data sets.
Google already seems to be moving in that direction with the Orkut plans and the (beta) publisher’s archive program, which digitizes publishers archives and puts them on Google services for searching–with ad revenues presumably shared with the publisher.
Note the Orkut terms of service: ‘By submitting, posting or displaying any Materials on or through the orkut.com service, you automatically grant to us a worldwide, non-exclusive, sublicenseable, transferable, royalty-free, perpetual, irrevocable right to copy, distribute, create derivative works of, publicly perform and display such Materials.’
