Wouldn't Inferno be a better fit for these sort of devices?

In my experience these things are used primarily as I/O devices,
with most of the CPU cycles going towards reducing/normalizing/marshalling
the data in and out.  Nothing I've ever built out of an ESP*,
Feather, Teensy, etc., would benefit from a full-on Plan9 kernel.

But having a fully-integrated 9P+auth stack would make these
microcontrollers a dream to integrate into a Plan9 environment.
