Valve has opened sign-ups for Steam's upcoming In-Home Streaming feature.

It still looks like an owl.

You can register your interest for In-Home Streaming now by simply joining its official Steam group, Valve announced (thanks, PCGamesN).

Closed testing will begin in the next two months - so before this year's end.

The streaming technology will let users play PC games on other machines within their house, such as those running Valve's upcoming Linux-based SteamOS.

In-Home Streaming is also designed to appeal to those who may want a Steam-powered box but not want to alter their existing gaming PC set-up.

"High-powered SteamOS living room machines are nice, and fun to play with, and will make many Steam customers happy, but there are a lot of other Steam customers who already have perfectly great gaming hardware at home in the form of a powerful PC," Valve's Greg Coomer explained during the announcement of the company's Steam Machines prototype.

"The prototype we're talking about here is not meant to replace that. Many of those users would like to have a way to bridge the gap into the living room without giving up their existing hardware and without spending lots of money. We think that's a great goal, and we're working on ways to use our in-home streaming technology to accomplish it - we'll talk more about that in the future."
