Last year, I had the opportunity to present an Office smart client training in Cairo, Egypt. It was one of those weeks I will not forget quickly. Awesome country, nice people and yes, they do SharePoint over there too :-). One of my former students (Mohamed Zaki) has a blog for quite some time now and he has made his first contribution to the SharePoint community with the creation of a nice little Windows tool that moves the files between sharepoint document libraries and keeping the version history and the directory structure of the files.
I am currently fully absorbed in the Office smart client technologies and have not yet found the time to test it out, but the screenshots like very nice. Try it out I would say and give your feedback to Mohamed.
