Thoughts on "Superdelegate Meeting"

The idea of a superdelegate meeting in June is being proposed by Gov. Bredesen.  

The purpose of this posting is to just get a conversation going about this idea since I have seen or heard little about it.  I'm not sure what the logistics would be but he is suggesting now on CNN with Wolfe that it would an open meeting held in a neutral place (not NYC or Chicago) with full coverage to the public.  
 

What do people think about this?  
What are the pros and cons of this idea?  
Do you think this will be necessary?  
Does this format favor one candidate over the other?
Do you think this will happen?
