Streaming from Win 7 PC to Ubuntu 14.04 Laptop faultlessly so far. If you have the means definitely give it a go. Might be time to build a steam box for the lounge room.

I'm sure it depends on your router, distance, how many walls are in between and of course the software running it. I was able to play Wolfenstein the New Order relatively well but there was some noticeable lag spikes here and there, as well as some lag input. For just it being a software update, it's pretty damn impressive.
Of course there are going to be some initial issues but I wouldn't knock it just yet. I'm pretty hopeful for this.
Edit: My experience was similar to that on the video, except my was over wifi on a wireless N router and my laptop does have a wireless N receiver. I wonder if an AC router will work better, as that is recommended for the Nvidia Shield.
I have had access to this for a while and it ran great form my desktop to my wheezy old laptop. The lag was not bad at all and that was on an old router that did not support N-Wireless. So it was going form my wired Desktop to my Wireless old Win XP laptop and it ran great, not perfectly but a hell of a lot better than I had expected.
Well I was just able to get it to stream to my Raspberry Pi using Limelight-Pi. I used this nice easy walkthrough on reddit http://www.reddit.com/r/raspberry_pi/comments/1vcmz9/streaming_pc_games_to_raspberry_pi_with/ . Now I just need to get a wireless controller for my PC...
Tried it today with the latest updates. Wow, much better than a few months back. Can now play skyrim on my T100TA whilst in bed with the gf. Really needs an -ac connection to get things moving nice.
My wireless router is too slow for game streaming. It works but there's just enough lag to make it annoying - thus I'm moving my router to the other side of the room so I can hard-wire my PC to the laptop (or HTPC when I eventually build one) for much better performance. :)
