I'll start.
As I mentioned, we've just come from a meeting with members of the Government of Southern Sudan and they mentioned to us that for Abyei, which is this region, a part of Sudan that lies in the middle between north and south, there will be a separate referendum deciding where Abyei goes. The members of what they call the GOSS, which is the Government of Southern Sudan—I think you'll be hearing from one of their representatives shortly—likened Abyei to Kashmir. So I think the analogy of India and Pakistan is probably a correct one, but also disturbing.
What's happening now, and this is encouraging, is that southern Sudanese who are in the north are already being encouraged to leave the north prior to the referendum. I think this is actually in some ways kind of helpful, because--you're absolutely right--we don't know what the consequences will be of the referendum. People tell us that we should know what the outcome is, but the consequences at this point are unknown. There will probably be some violence; how widespread, we're not sure.
One area for us to focus on is this area I mentioned briefly, which is to get the government in the north to agree that southern Sudanese who find themselves in the north, if the referendum goes in the way of separation, are recognized as Sudanese nationals. We don't have that guarantee yet. As I mentioned, we have that guarantee from the folks in southern Sudan, but relating to northern Sudanese, we don't have that guarantee as of yet.
