if both PCs are on the same network, you could try symbolic links to the "main" PC. I tinkered around with it, basically made a folder called "CDLC" on the 2nd PC in the "rocksmith/dlc" folder, then used a tool to create a symbolic link pointing that CDLC folder to the folder on the main PC where the files are. The 2nd computer sees that folder and link and as long as both PCs are on and not asleep or powered down, the 2nd PC essentially loads the songs from the main PC. It worked when I tried it a couple months ago, but since then have just been playing on my main PC and haven't tried it since. It might even work if you have all your CDLC on a usb drive, so long as the usb drive is plugged in and recognized by the PC before starting Rocksmith (so the song files can enumerate at start up). I might have to give that a try just to see if it can be done . . .
