Ha, the first thing I searched for on this thread was "raspberry". I just got mine last week. However, there's no way in the world that thing will be able to run modern games.
I have a spare Pi laying around, and I'm hopeful at least. According to the SteamOS page there's a streaming mode where you basically do the processing on your Desktop / Server, and SteamOS just takes care of input and streaming.
Fingers crossed !
Or SteamOS inside a Docker container!
;-)
This actually isn't a terrible idea. It's been a _long_ time since I've gamed on Linux, but I remember playing Tribes 2 in aeons past, and had to patch a decent chunk of the libraries in my distro to get it working. Using something like Docker/LXC to define the runtime environment of a game would probably help to make life a lot easier.
As long as the use of containers didn't impact on performance too much, which ideally they don't compared to virtualisation. (I say having not personally had any significant experience of the different performance characteristics).
Why not, each distribution/DRM platform can go in its own sandbox... ;)
