Thanks for the reply lilsniff - yeah I was aware of this but I don't think anyone has ever been banned for it.
Also, they've specified cloud-gaming in that post which specifically removes local remote access from the picture (which is what I'm referring to).
You would imagine the thousands of multiboxers that use VM's and stuff to play WoW would have been banned by now.
There is also the Geforce Now side of things as well, which is clearly Cloud, and they had no issue with people playing their games remotely.
They've removed their games from GNow at the moment but that's unrelated to T&C's as far as I'm aware.
So, I don't think Warden could detect what I'm running on the second PC, so I reckon it's an extra layer of security.
Unless they've some other methods... .but it'd be nice to hear from anyone that's tried it out.
I'm using the below as a means of playing WoW on an old Surface Pro 3, streaming off my desktop and it works flawlessly.
