Give SO2R a try. One will quickly find out that it is definitely NOT an automated second operator. Learning to decode two separate audio streams would be trivial for the technology behind skimmer. It is non-trivial for a human being to learn and it takes a big commitment to master. It is hard to program a computer to automate "commitment".
