Although getting the approval nod would be wonderful...acquiring patents and other progression of sorts "isn't" a waste of time. Sitting at a empty table in the dark,twiddling your thumbs, and waiting for approval "and not" doing anything else of value is a waste of time. We still need acceptance..acceptance is all that we need but until then...the more "shit" we have the more value we have..even though with out that acceptance it seems invaluable.
