Guys, there is a company called 'Frenesius' that has a BCM product, of which I found it to be less superior than Sozo (or L-Dex) as it measures only across 50 frequencies and are not able to even detect changes in impedance if you've drunk 1 litre of water. Frenesius is a $24B Euro mkt cap giant and specialise in the kidney space.
I believe that the next blue sky for Impedimed to tackle after lymphedema and Congestive Heart Failure market is in the kidney space! (note that I still think that general consumer use of Sozo is a side-income). Plenty of $$ to snatch from the giants! Obviously it's a good thing to not overspread itself upfront and tackle the first 3 markets (Lymphedema, CHF, Fitness) first, then once the company is more established, let's go for the bluer skies!
Some useful references on how BIS can be used for kidney patients as per below:
