I'll edit in more info as I find it.  
Obama Blog

Former Senator Sam Nunn said, "America remains the strongest nation in the world, but we can only be successful in tackling our toughest problems if we gain cooperation at home and abroad.  Our next president – working across party and economic lines – must restore and strengthen our national purpose, our credibility, our competence and our spirit.  

"We need a president who has the temperament of a leader – a sharp, incisive, strategic mind, a rare capacity for self criticism, and a willingness to hear contrary points of view.

"Based on my conversations with Senator Obama, reading his book and his speeches and seeing the kind of campaign he has run, I believe that he is our best choice to lead our nation.

Former Senator David L. Boren said, "I am joining Senator Barack Obama’s advisory team on foreign policy and national security because I believe it is my duty as a citizen to do all I can to help our country at this critical moment.  Our strength is declining.  Eighty-one percent of Americans believe we are headed in the wrong direction.  We must act quickly to meet and overcome the challenges we face.

"Our most urgent task is to end the divisions in our country, to stop the political bickering, and to unite our talents and efforts.  Americans of all persuasions are pleading with our political leaders to bring us together.  I believe Senator Obama is sincerely committed to that effort.  He has made a non-partisan approach to all issues a top priority.

Sam Nunn

Samuel Augustus Nunn, Jr. (born September 8, 1938) is an American businessman and politician. Currently the co-chairman and Chief Executive Officer of the NTI (Nuclear Threat Initiative), a charitable organization working to reduce the global threats from nuclear, biological and chemical weapons, Nunn served for twenty-four years as a United States Senator from Georgia (1972 until 1997) as a member of the Democratic Party. His political experience and strong credentials on national defense reportedly put him into consideration as a potential running mate for Democratic candidate John Kerry in the 2004 Presidential election. In late 2007, he commented on the possibility of his running for President of the United States in the 2008 election as an independent candidate.[1]

David Boren

David Lyle Boren (born April 21, 1941) is an American politician from the state of Oklahoma. A Democrat, he served as governor of Oklahoma from 1975 to 1979 and in the United States Senate from 1979 to 1994. He is currently president of the University of Oklahoma.

Halperin classified this as support from the center.  I believe David Boren was apart of the Unity '08 ticket that was promoted by Bloomberg early in the year.  Both have joined Obama National Security Foreign Policy Team.

Neither are superdelegates that I can tell...

Update:  Lots of handwringing that these guys are DINOs but the fact is that Obama is going to be the nominee of the Democratic Party.  We all seem to regard this as fact these days so he's going to get a lot of DINO endorsement b/c that's what we want, right???  I think he's going to get the endorsement of popular NY Senator who is currently drawing our fire in a few month too.  It's up to us to make sure that Obama holds on to the ideals of the people that got him there!
