In order to 'trick' the Xfinity app, I apparently need to be able to spoof the IP of my Xfinity router which is what the app uses to check to see if I am home or outside - and that might be a harder techie thing to pull off on an iPad or Android tablet unless there is a way to do that given I am on wifi behind a ATT Uverse router.
Yeah, the VPN's performance in general is going to depend on your upload speed at home. For instance, I pay for 200mbps download and 20mbps upload and even if the hotel or other venue has a much faster connection, I only get 15mbps or so download according to speed tests.
As for video, I'm not sure how Slingbox is encoding video but it's possible that the Xfinity app uses better encoding that allows the same video to be transmitted with less bandwidth. It's worth a shot anyway if you already have the Pi.
