The latest deal has broken down. I'm interpreting this to mean that Zelaya did not think he could win a vote in Congress, and so is trying to stall. Delays only help Zelaya, since the interim government of Honduras is diplomatically isolated, and elections held while it is in power may not be recognized by other nations.
What a stinking mess. And the U.S. was central in creating it. Had we strongly supported Micheletti from the outset, or at the very least made it clear that other nations should butt out of Honduran internal affairs, this crisis might have been over months ago.
