That is a big misconception about Vue. You do not need a Playstation at all. I know there are PS Vue apps for Roku, Fire TV, Apple TV, etc. I currently use a Nvidia Shield(Android TV) which can be a little pricey but very good speed. As far as a VPN, PS Vue usually doesn't like them as they end an error message that you are not watching in the zip code in which you account was set up.
