Launchbox is extremely portable especially in the way that you wish to set it up. The easiest way to set it up over the network is by using paths directly to the other network computer although using mapped network drives will also work as long as you assign the same letters on the PC that you move it to. I use paths like this on mine \\servername\Emulators\Platform\Games this way I can simply copy my LB install to other machines and they will work after I change the paths to my new emulators on the other computer.
