Obama to speak in Cairo?

The NY Times has speculated that Obama will be possibly making a historic speech in an "unnamed Islamic capital," most likely Cairo, Egypt within the first 100 days of his administration.
This would be a bold move, and possibly the first time since 9/11 that a major western leader has made such strides to try and address the rift between the western world, and that of muslim-majority nations.
Security would be massive, no matter what, and what if he fails? It would be a pretty big smear on Obama if within the first 100 days of his administration he delivers a huge speech with a completely worldwide audience -- targeted at people with whom the US has somewhat chilly relations -- and falls flat on his face.
It would have the possibility of being a Reaganesque move towards reconciliation, or a Bushian move towards deeper hostility.
