Don't be disheartened by the lack of response. The product looks extremely impressive, but I suspect many here don't have a use for it. I like to give feedback by thinking "if I were king of the zoo, I would do <this>". In this particular case, I have no idea what I would do, because the software is not something I need or want to use. So I don't really have any feedback to give you. However, I can certainly imagine business folk using this tool and being very happy with it, particularly if they are already using Google Spreadsheet, so I think you've got a winner on your hands. Try asking for feedback on the JoS Business of Software forum (http://discuss.joelonsoftware.com/?biz http://discuss.joelonsoftware.com/?biz). There are probably some potential customers there as well.
