While google said that it didn't see businesses using it, some companies that are quite sophisticated in their use of social technologies, such as Ford, are already using Google+ as a business tool. In a nifty way, Ford is using the 'hang out' multiple user video call function to hold live chats with execs.
I can see companies quickly using the other functions to help their communications efforts. For example, Circles, the friend grouping function, could be used for getting useful information out to targeted groups of journalists and bloggers.
Google says a corporate version of google + is coming out later in the year. Can't wait:)
