That would be fun to get a 9p sensor platform up and running.
I was thinking about writing 9P client/servers for Arduino. Developing for Arduino is SURPRISINGLY easy--at least on Linux--you just install the gcc avr cross-compiler and avrdude, untar the Arduino library source, tweak the Makefile, cut-and-paste some skeleton code, #include standard stuff you want to use, run make, and use the open source program avrdude to upload the image to the microcontroller over the FTDI USB serial interface. I've done a lot on Linux, and it really suprised me how straightforward it was programming the Arduino. I looked around to see if there was a canonical 9P implementation that I could use as a starting point. Alas, I found about a brazillian different implementations, in about as many languages. If there was canonical 9P client/serever skeleton code (in C, pseudocode, or some other language) with "fill-in-your handler" placeholders, it would be really straightforward to implement 9P clients/servers on Arduino. ...with one caveat, related to underspecification of the 9P protocol, which I will ask about in a separate thread: "9P specification: minimum number of fids".
