A bullet point list of materials, a paragraph of description, a few diagrams and an embedded video demonstration would be far more effective. A slideshow would also work well.
I apologise if this seems nitpicky, but as interesting as I found what you've done, I only watched half your videos because I found it so painful to sit through them. I doubt I am alone in this.
The rest is irrelevant; if a game runs on the SteamOS, it will run on my Linux desktop.
Considering there is already Steam for Linux, its probable that Valve will ensure Linux games run on both platforms equally well.
In any case, if there is no need for "all the trimmings", if Valve just wants to make an entertainment pipeline, then that's fine by me. It's the same kernel; this is a huge win for Linux by any measure.
