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.
