Protect and Serve is a server that protects.8-) Protect and Serve is free. But, of course, that is an illusion. Nothing is free. Buyer beware. You need to understand what you are doing. That's why the State Bar ethics opinions all say that a lawyer has to take active responsibility for the technology she uses. If it goes wrong, you can't blame a vendor. If you want to keep your data confidential "in the cloud" it has to be encrypted. But it also has to be easy to get at, and **there must be no risk that you will be locked out of your data, ever**. I'm an attorney as well as a programmer. And I want to use Dropbox and Google Drive and link these resources with a cloud-based law practice management product. I want my documents in the right place, but attorney-client privilege is the big issue. And the second issue is that I don't want to find out that I am locked out of my own data one day because of my need for confidentiality. I developed Protect and Serve for my own use. But plan to release an early version soon. It combines [[http://en.wikipedia.org/wiki/WebDAV|WebDAV]] shares and the [[http://nodejs.org/|node.js]] encryption layer that uses [[http://en.wikipedia.org/wiki/OpenSSL|openssl]], through a crypto extension to [[https://github.com/mikedeboer/jsdav|jsDAV]]. All the technology is open-source. Protect and Serve uses the same [[http://opensource.org/licenses/MIT|MIT]] license as jsDAV.
