 Hi Martin,
Thank you for the pointer, interesting article.  :-)

I don't have any experience with professional mic's.  I am guessing this is a big chunk of the expense?
The converter is not expensive.  I2S (1.4 Mbps max.) doesn't sound fast enough (192 Ksps * 18 bits = 3.5 Mbps), but there are many options for capturing the converter's output.

 I wish for a high data rate 16-18 bit ADC module like this https://www.adafruit.com/product/1085maybe using I2S to get the data rate up to where it would work for ultrasound 192 ksps or higher would be ideal.
If it would work with a modern higher clock rate arduino or a RPi that would be perfect.
I would deploy them to record sounds of bats in the rainforest canopy and collect the data with WiFi.
There would be many other uses.  Hydrophones, HiFi recording, 
Right now the gear to do this is really expensive
