It may be cheaper, but also totally fail for now. So while you might put 1$ at failed program, it is not an argument, tell me of a succesfull reveng program and how much it cost. With fully open base costs should decrease dramatically. Your argument is: it is so costly, noone ever done it, so lets build a device from scratch, which accidentaly also was never achieved by anyone in a satisfactory fashion... how can you compare price???
