other OSes

this seems to suit our purposes.

I mean we would have to right drivers for divices attached.

and it can work with 16 bit processor and smaller than linux.

so we could view using this os as what i would have to write anyway. and there is nothing to stop the devlopment of a package for linux to accept data in the format which this nodes use. and be able to process it.
