Kara Swisher over at Boomtown claims that Microsoft is close to a non-exclusive data mining deal with Twitter that would bring real time tweet results to Bing. According to her sources, an announcement on the deal could come as soon as the Web 2.0 conference in San Francisco, which is happening this week. Twitter is negotiating with Google, although sources say the Bing deal is likely to be finished first.
If you think you may have heard this all before, you have (sorta). Back in July, Hsrry reported that Bing had begun to integrate some tweets into search results. This mainly was just a test, and limited to certain prominent twitterers.
It appears however whatever is going on here might be more extensive. Tweets would be available in real time, and would probably be spread out across any search, rsther than just for searching specifically for the tweets of a certain person.
