Turn it down! Politely decline. Say he's honored but he hasn't had the time yet to accomplish what he wants to accomplish. Result: He gets at least the same amount of glory--and helps solve his narcissism problem and his Fred Armisen ('What's he done?') problem, demonstrating that he's uncomfortable with his reputation as a man overcelebrated for his potential long before he's started to realize it.
I think that would indeed be Obama's best course for dealing with his 'all hope and no change' Nobel. But I also think there is no chance that he'll decline it. Nothing in his career suggests that he is the least bit uncomfortable with being "overcelebrated for his potential."
