This has been clearly coming — some start-up companies tried it with limited success. But now Google unleashes Goggles to point to interesting things using your mobile phone and find information about real world objects from cyberspace. A kind of connecting part of real world to cyberspace. See http://www.nytimes.com/2009/12/20/business/20ping.html?_r=1&sudsredirect=true.
I think this is the beginning of a new application area for lots of people. Many interesting applications to be expected in this space.
