Chrome on Android lets you bind your phone/tablet's localhost to your computer's localhost. This enables you to test during development, even if your corporate IT people disallow connections between devices on the same WiFi network (or partition personal devices onto a different network than corporate hardware).
Hey that's a neat trick. If I'm reading the docs[1] correctly, as far as the application is concerned it is connected to the loopback. The same thing happens when I `ssh -L <port>:localhost:<port> <local-vm>`.
I think it also follows the spirit of the idea since the change is local to the machine you're using.
