I was actually thinking about your product when venting my frustrations elsewhere in the thread. Your site was mentioning elsewhere that you had a working shoebox-sized device which, "due to its size", was "only targeted at hospitals".

Man, you have no idea. I'd gladly buy a shoebox-sized thing. No finger pricking and no test strips to buy is the king. It could be 4U rackmount thing for all I care, as long as it was noninvasive and accurate.
