You can store the documents on a subversion server not on your computer.

What is the difference?
I run a subversion server on my PC and on my MAC. This is very easy to setup. If you like, I can post the instructions needed to setup the svn server.
I trust svn is secure, but I only allow access on the Intranet. I have other external users accessing the repos, but they can only access the repos via a HTTPS tunnel.
This is also easy to setup.
BTW, I have given up on using a dual boot. I use vmware exclusively. I upgraded my ram and run vmware in Windogs. Works great.
For private use, running a subversion server is dirt simple.
BTW, I have not tried a non cygwin version on Windogs, but that should be easy. I am sure you can find the exe files on the Internet.
