I think this hits on a big stumbling block for the product. There are a huge number of companies that don't allow the data to be removed from their workstations or servers. If the product could be implemented as an extension for Excel, similar to Xobni in Outlook, then there is much more potential. There is really no reason for this to be an online app.
