What would be possible is to build a general purpose
building block. Something like this:
- provide a tiny thread library
- provide 9p over USB|serial|UDP
- implement a simple 9p server framework & export a server
  side interface where one can plug in sensor/actuator
  specific routines and specify the FS layout via a string.
- implement a namespace convention for discovering
  capabilities (for example a "help/" dir)
- it should be implementable as a verilog block some day!
  may be not but imagining that keeps the design simple.

Actually it doesn't have to be 9p. It can be something
simpler.
