I don't know your end goals for the project, but you may want to look at Novell's iFolder. It allows you to access and sychrnonize files from any internet connected computer and encrypts the data when it is transferred. I believe passwords are encrypted also, but am not certain. We are going to be deploying this at my place in the next few weeks and make it accessible through an ssl vpn (never enough encryption) and it looks like a winner for our project goals.
