Clinton/Obama ticket?

On CBS news this morning, Sen. Clinton answered questions, including one about the possibility of her and Obama running on the same ticket.

The question is, assuming that Clinton gets the top spot on the ticket, would it be beneficial for Obama to be VP? In terms of winning the general election, I don't think that people who don't like Clinton are going to be any more likely to vote for her because Obama is on the ticket. And moreover, does he want to be in that position? Its likely that Bill Clinton will be a VP in his own right. Going on the previous Clinton presidency, who doesn't remember the attention and focus on Hillary's healthcare concerns as opposed to Gore's environmental concerns? No matter who the Clintons tap for the VP spot, that person has to contend with the fact that this is a far from usual situation.
