Late Update: A few readers say the two shook hands right after the conclusion of the debate, at that moment where Brokaw told them they were in the way of his teleprompter. Here's what TPM Reader KP said ...

Hey, i watched the video of the debate. The moment right before Tom Brokaw told them they were in his way, they clearly shook hands vigorously. Then they took a moment to stand side by side for the audience and Brokaw was like, hey move it.

The moment you showed on video was when McCain was obviously presenting his wife to shake Obama's hand.

On the other hand, in the video above, Blitzer seemed to think they had no yet shaken hands.

Special Late Night D'oh Update: It turns out KP's right. They did shake hands right at the end of the debate, at the point where they got in the way of Brokaw's teleprompter. It wasn't on CNN or NBC but we just found it on ABC. No question. They shook hands before McCain later snubbed him and then ran off in a huff.
