So what "proof" are you looking for? No other REM device has ever proven anything... nothing at all. So I really don't have that as a model.

I've offered the graphs and the raw data more than once.


The $200 was mentioned by someone else. What is *your* pricepoint? That is certainly in no way indicative of what the cost might be. I'm gauging the market. If the market is willing to pay something that makes producing the device worthwhile - then it goes forward. If the market isn't - then it remains a neat idea that sits on the shelf until either A) the market will pay for it or B) the cost of producing the unit can be brought down.

Seriously, guys, I'm looking for input on price and feature-set. Be realistic. Also, the "proof" thing. What are you looking for there?
