Marc has the latest. He says Gov. Kathleen Sebelius, Gov. Tim Kaine,  and Sen. Evan Bayh are under serious consideration and that Biden is also under consideration but not experiencing the same level of vetting. Marc's analysis:

Sebelius and Kaine are both governing choices, not campaign choices. They're not going to match Obama's enthusiasm levels; they're not going to do all that well at the VP debates; they're not even going to solve political problems (even Kaine).  But they are solid; they are centrist-in-style; they are Washington outsiders; they know how to balance budgets and deal with Republicans. As an historical analogy, think Clinton's choice of Gore.

Choosing Biden or Bayh would put in the White House strong and knowledgeable legislators who would be expected to do heavy lifting with allies and adversaries. both would do well at the debates; Biden is flashy and might upstage Obama, but he'd be the best sheer campaigner and his selection would bring a jolt of enthusiasm to the Democratic ticket (as if it needed more).  The downside here is the same as the upside: the focus will be on the ticket and not on Obama, per se.  Bayh and Biden would call attention to Obama's manifest lack of engagement with American foreign policy. And Biden, in particular, would face a prolonged period of press recapitulation. (And could Obama trust him to keep his mouth shut?)
