I have a VMware ESXi box at home that I use to run a Windows VM with a video card passed through. I've been using it to stream Heroes of the Storm with Steam's In-Home Streaming and I get a consistent 30 FPS (1920x1080) with no noticeable lag.

Admittedly, it's not exactly the same as the setup in this article since it's not streaming over the internet, but I would assume that as long as your latency is low and bandwidth is high, you'll have no problem with this setup.
