pra quem usa DotNetNuke: um file manager com drag&drop

hmmm... parece interessante: nao só é feito em Silverlight como pode ser completamente customizado: 

This project uses the View Model Style pattern that allows for a complete separation between program and design. This allows a Designer with no programming ability, to completely change not only the style and look of the application, but also the entire design of the application.
