The Sunshine/Moonlight combo allowed me to stream emulated, upscaled SSX Tricky (PS2 game) from my desktop to an (at least 7 year-old) Android streaming box as smooth as silk.

The only downside was that the game had to be running, visibly, on the screen of the desktop machine, meaning the desktop is unusable for anything else - ie. if someone else wanted to play the game while I was working on the desktop.

This appears to solve that. Sunshine/Moonlight was already cake with a fair layer of icing. This is a sprinkling of glacé cherries on top. I love glacé cherries.
