Steam Link beta build 688 introduces Steam Link Anywhere, which gives Steam players the ability to stream games from any computer running Steam.
This new system removes the old restriction of having your devices on the same WiFi network. It’s also currently in early beta mode and thus users should take it with a pinch of salt.
A post from slouken on the Steam Community boards stated that you should be able to stream games to your Steam Link from virtually any computer running Steam.
The only requirements are a good upload speed on your computer and a good network connection on your Steam Link device.
Steam Link Anywhere means that as long as your internet connection is stable and you don’t mind having a computer running while you’re out, you should theoretically be capable of playing games literally anywhere.
On the bus, at your job, while lying on the bed next to your computer because you’re too lazy to move – anywhere.
Steam Link allows you to play on your phone, tablet, or TV for free using an app from Google Play. It should be added that iOS users are currently out of luck, as Apple keep rejecting Valve’s attempts to get the app on the App Store.
As of right now, only Raspberry Pi, devices running Android, and the discontinued but still usable Steam Link hardware can support the Steam Link Anywhere beta. It’s currently unknown what devices may be added in the future.
