I reinvented this method, except using a coin flip, during an urban economics class. We were going to actually conduct surveys in the Detroit area and thus had to learn about the problems with surveys. However my professor didn’t seem very excited and pointed out some incentive shortcomings (I was too disappointed to listen too closely), and I got the impression that this is a known method with known limitations.
