I am really disappointed that this awesome concept didn't go anywhere as I really loved it to the point that despite mounting evidence that it is abandoned I still come back every few months desperately hoping to see that some progress has been made on it. However despite my disappointment I acknowledge that sometimes things just fall through or that life can get in the way and I hope that you are doing well whatever you moved onto
