Friends can now ping shows and films to your TV via Google's Chromecast streaming dongle without needing to jump on your Wi-Fi network.
The Android app was recently updated with a new guest mode. Enable it, and every device in the vicinity will be able to stream whatever they want to the big screen.
Once you've enabled it over Wi-Fi, you'll get a randomly-generated PIN. Anyone who wants to stream will need to enter the PIN to gain access.
They just tap the 'cast' icon that appears on their screen, and then play the video. And hey presto, it appears on your TV.
It should be handy if you don't want anyone and everyone hogging your Wi-Fi whenever they come in range of your flat, and you don't fancy changing your password after every time you have people over.
The mode is only on the Android version of the Chromecast app at present. There's no word on when – or if – Google will bring it to iOS. Could it leave its Apple-owning cousins high and dry? We'll have to wait and see.
Here's a demo to see how easy it is to set up.
