I'm with Larry, Rio sounds like it is the place to be for NYE ... I plan on going, but perhaps 2012 ...
Brazilians definately know how to party!
Alternatively you could go to Mazatlan, Mexico. Start the day with a tour of the Pacifio brewery and enjoy tasing the beer ... and its not just a tiny glass... you get to taste a whole bottle ... as many times as you want! and then you can wander to the beach and check out the Locos ... ie crazy cliff divers ... and then party it up with the locals!
Or, there is always Egypt ...
