I like the concept but question the business model.<p>It is something with universal appeal but I fear the revenue from "extended" won't be sufficient to sustain it over time. The value add just doesn't justify the subscription price --- considering that I can achieve similar functionality on my own using Aescrypt and readily available "free" web storage.<p>To make it more viable I would suggest extending the functionality. In particular, I would like to see an option for asymmetric encryption. Distribution lists <i>with</i> notification. I would like to upload a file that only select individuals can decrypt <i>and</i> have them notified that the upload is available.<p>Discuss amongst yourselves and get back to me.
