You can install TR on a Raspberry Pi, since it comes with JRE installed on its ARM architecture.  You install the Linux version that does not have JRE included.  The Pi also comes with a licensed VNC, so it's possible to get a remote desktop on a fully working TR and use that as a centralised system, even using an iPad or iPhone as your viewer.  Results vary but the concept works fine.  It means you can securely access the complete desktop from anywhere in the world.
