I think you have the right idea.
owexternal is a protocol to use non 1-wire devices as 1-wire slaves.
Obviously we can't use normal 1-wire reading, writing, IDs or selection.
Instead the device is described in a file with links to programs that do
the actual communication and return the result.
owexternal is actually already built into owserver. It isn't well tested
since I had no actual use case, so your help will be very appreciated.
This is the documentation:
