OK, I certainly would not dispute that.
However, 5 months down the line, you must at least have formed a conclusion as to whether MLat will require new hardware, or will be possible with the current box. Can you share that with us ?
Speaking as one of a small number of individuals who knows what's involved in developing MLat solutions using enthusiast Mode S receivers, I'm sure you will forgive my natural scepticism.
