The portable version has all of its settings and cached files etc in one folder that you can share on the network.
Such a setup won't work if you need to have more than one location open at any given time, but you shouldn't be doing that with a shared library for the potential of corruption anyway.
I use it this way for my own use in the house on three computers, and the advantage is to have only one set of settings to change when I want to adjust something and only one copy to update when a patch is released, which is frequent. Keeping multiple copies up to date and looking the way you want is tedious.
