Google starts streaming some Android applications

In addition, you're also going to start seeing an option to "stream" some apps you don't have installed, right from Google Search, provided you're on good Wifi. For example, with one tap on a "Stream" button next to the HotelTonight app result, you'll get a streamed version of the app, so that you can quickly and easily find what you need, and even complete a booking, just as if you were in the app itself. And if you like what you see, installing it is just a click away. This uses a new cloud-based technology that we're currently experimenting with.This seems like a hell of a lot of work and infrastructure for something that could be solved by, uh, I don't know, installing the application?I'm getting old.
