If you want to do that you already can with splashtop, but with splash top you can do android and I pad/phone. As for streaming to a laptop, you can already do that with windows 8 Remote Desktop. Not sure what use steams is, maybe for Linux and Mac.
No luck getting it to work so far with 3 or 4 games I tried. The game starts on the host, then Steam crashes.
The old PC I'm trying to stream to has outdated video drivers so I'm updating those now to see if it helps.
