"Democratic strategists, including many linked to Congress who have battled the Bush administration for the past eight years, say such a spirit of comity is long overdue. It's unclear whether it will last much beyond Inauguration Day".

Two to one it doesn't last 24 hours, or until Jimmy Carter finds a reporter with a microphone.
I think Carter's public attacks on Bush have been over the top. If he can put them aside and be civil to Carter, I think it shows W's got one thick hide.

I wonder if Jimme will bring his foreign policy advisor daughter Amy with him?

On the whole, a good gesture by Bush.
