In my humble opinion, your comment is unwarranted. I never said that it will never work.
I actually spent several days last summer evaluating and developing prototypes on top of platform APIs (e.g. TokBox, Sinch) and tested the call quality in several different situations (moving from WiFi to 3G, dropping and regaining signal during the call, call behavior while moving in public transport etc.)
I described my experience and conclusion, hoping to spark informed discussion of the topic. Your comment didn't add any information to it.
