He may be Mr. Platitude in public, but he's getting the work done

Sudan Envoy Gration is in Sudan now, and seems to be getting parties to keep rolling towards the referendum, getting them fully engaged in compromising. The details are fascinating for the political science junkies I suppose- should southerners in Khartoum vote in the referendum? What if they are Khartoum residents but come down to the South for the vote? How does one tell who is or is not a resident of the South? Is a northerner who is in the south during the vote eligible to vote in the referendum?

In some sense it would have been preferable for the referendum to have take place at the same time as legislative elections... that way most people would have had to decide whether moving to vote for the South outweighed staying and voting for local affairs. I'll be curious how the cross-border vote issue gets settled.
