Interestingly, I REALLY want the exact OPPOSITE of this.
Many times it's just so frustratingly difficult to take a screenshot of something on a computer screen and send it over one of the several mobile messaging apps that don't have a good desktop client, so I end up just taking a picture of the physical computer screen with my mobile phone. It looks like shit but I'm lazy. I really wish a piece of software could recognize what I just took a picture of and then pull the actual data from that portion of the screen, send the screen data over bluetooth or Wi-Fi or whatever to the phone, and "fix" the screenshot.
