There has been occasional speculation about an Obama-Bloomberg ticket. One criticism of it was that Obama would get New York regardless, so Bloomberg doesn't help deliver a big state in which Obama could use help. But with all the reporting lately about Obama's difficulties in Florida and in particular with its large Jewish population, maybe Bloomberg could make the difference. Apart from that, Bloomberg does bring strong economic credentials to the ticket, probably stronger than anyone McCain might pick, along with the "executive experience" some people feel Obama should be looking for. And he has mainstream/centrist appeal for those who are worried that Obama may be too liberal. Seems like a potentially good match to me.
