A bit OT but I am not sure it deserves a new thread: dirvl, you might possibly make some buck by producing a "universal prototype TOH". Perhaps in two varieties, just the plastic cover and the plastic cover plus a universal PCB with the connectors at the right places. Perhaps even a third variety, same as #2 but with the I2C chip and some Arduino or whatnot soldered on.
In fact I think Jolla should provide such dev kits. That would definitely make the TOH concept more attractive. The "dev kit" they provide now is a joke.
