I got VPN working on my shield... Quality is pretty good over LTE although with a lot more audio delay but that could just be LTE.
Step 1. Go to the Network and Sharing center and click the Change adapter settings button
Step 2. Press file -> new -> New Incoming Connection. Mirror settings below
Select user that you use. This will have the same user/pass as your computer
Step 3. Go to settings on your shield. Go to more -> vpn -> plus button (you may have to set a pin or pattern if you don't already)
Enter a name, your external ip address (or dynamic dns)
Step 5. Open the port TCP 1723 and GRE on your router. On fios actiontec this can be found in Port Fowarding and using the "PPTP" preset service.
Step 6. Click the new VPN entry on your Shield. Login and if all goes well it should say "Connected" YAY!
