Talking is better than killing. What happened to President Bashir's direct talks with Darfur rebel leaders?

On scrolling through the archives of this blog, I found Gaddafi will urge Sudanese President al-Bashir to hold direct talks with Darfur rebel leaders.

What happened? What is so difficult about President Bashir sitting down at a round table with all the rebel leaders and getting the Darfur-Darfur Dialogue started, for the sake of Sudan's children? Where's Jan Pronk and Libya's Col Gaddafi? Why are they so quiet? When are they planning the Darfur-Darfur Dialogue Conference?
