This is very nice. I am interested in whether or not an open source library was used for much of the processing, or if it was written from scratch entirely. If there is no open source library available to convert stylesheets+HTML to inline CSS, it would be a good idea to consider open sourcing some of the code behind this app. Either way, very nice app - great job!
