I know little about this, but from reading the description this sounds like a replacement for the "server" side of it (running on the machine where the game is running), but the article is talking about ending support for the client side of it on the Shield (please correct me if I am wrong)
You're right, I got them completely mixed up (I was incidentally looking at streaming from Linux the other day, and googled/ported without properly reading)
In which case, perhaps a better replacement is something like this: https://github.com/moonlight-stream/moonlight-android
