I don't think that this will be ultimately consumed by a lot of end-users. If I am that far away from home I'd just log into Steam on whatever device I wanted to play on. Even if it wasn't my machine...with Steam Guard it is decently safe to such things these days provided you remember to log out.
Granted it would be nice to use the horse power of my home rig and play some more CPU/GPU intense games, but...even if you could maintain 75Mbs through the entire Internet connection you are going to have issues with that much graphics data getting tossed around. For easy to run games it will probably be fine, though my laptop can run those anyway. I've done the in home streaming a few times and I haven't researched it deeply, but I've seen it consuming over 75% of a 1Gbs network on the few games I've tried it on according to Windows Task Manager. I would think it should be using more than that if I did the math, but I am guessing there is some compression. Though things can only be compressed so much.
However, I could see a publisher streaming out game files as they are needed instead of having the user download everything in one chunk. Perhaps a thing like EA boasts on Origin where you can start playing before the download finishes (but I've yet to see that actually work on any game on Origin).
