It is a shame Windows gates this behind their business edition(s) as it could really cut down on waste, especially now that streaming is becoming practical.
I recall trying this with Linux and it worked reasonably well.
Yes I can see this previously being limited and setup specific if it means being confined to wires/same room, but with decent wireless, people are running this with cheap headless client like Pi+Moonlight or Steamlink on monitors in another room. Even a few years ago I had to run a network cable to my steamlink. But now it's streaming at 1080p60 with very little latency and frame loss. But so far, diverting $$$ to have a faster computer with more cores, and better GPU, and faster wireless networking, and a faster media centre than I would have otherwise cobbled together has been win-win-win.
