I have been researching but I don't see anything on the subject, but is there a way to install an svn on a MyBook Live?
You can install OpenVPN with the FeaturePacks.
It works well and good services.
You can install any software on mybook live, just like you install sw on you PC,
it has enough disk space and CPU/RAM is also good.
Now I have installed many packages on it, like git and cvs.
I also install nginx http server and shudown the original apache2.
