If you are looking for a brilliant speaker for a conference, consider Chad Hower. As you might know, I make very few endorsements of that sort. Chad has been touring the Middle-East and Africa region for Microsoft in the past several years and spoke at countless conferences. And there might be is no better source for "travel war stories" than him; the stuff he's been through on his trips makes my (known to be extensive) travel history pale in comparison.
Chad is leaving the company in a few days from now and I wouldn't know anybody here who wouldn't be sad to see him go. The good news is that he'll be an independent speaker and if you run a conference or a user group anywhere in EMEA, you should really consider have him come over and talk.
