Great news re: Sudan?

The Washington Post reports:

With a prod from the United States, the government of Sudan and the biggest Darfur rebel faction signed a complex peace plan yesterday that diplomats and experts said would require careful implementation to ensure an end to a conflict that has left as many as 450,000 people dead and 2 million homeless.

Deputy Secretary of State Robert B. Zoellick, who pushed the parties to an agreement during three days and nights of almost continuous negotiations in the Nigerian capital, Abuja, warned of the tough task ahead in a conference call with reporters.

Here's hoping . . .
