Just for anyone that's interested, I've started using the xbox game streaming app to stream to my phone while at work to refresh afk processing and fishing and it works great. Doesn't seem to data heavy atm and reasonably playable, tho I wouldn't wanna farm to test it atm. 

Think if your part of the preview program anyone can set it up, although it's not quite the same as xcloud it works well enough for life skilling on the go
