so your position is that there's significant unrealised demand out there, but no commercial company has bothered to satisfy it and make a profit out of doing so, any only you're got the unique insight to perceive this? riiiight. I said much the same thing over seven years ago, and that passage of time has proven me correct. it might not take another seven years for things to actually change, but come back to me when you can buy the gear off the shelf at JB Hifi or Harvey normal. that's when it's consumer grade.
