@SteveClough@cstross I get the desire to keep such cutting edge research in-house, but if that house has collapsed, the source code for driving devices already installed should be made public. That would at least allow other people to take up maintaining the software either on a volunteer basis or being hired.
Personally, I wouldn't be comfortable having any devices installed in me that I don't control in their entirety and that means being able to install my own code.
