+1 regarding security/privacy concerns. I also was considering using EN for customer/client data because of its great abilities to search inside of scanned images (such as forms that have been filled out by hand). While the sync options are nifty, it could be disastrous if there were ever a programming mistake that made everyone's private notebooks public, even for a brief period of time. I wish that there were an encryption option wherein we could define our own key, much like what Mozy does with their back up service. In the same vein, it would be wonderful if the new EN were HIPAA compliant.
