This actually looks fairly interesting--from the overview paper it
seems to be nothing more than a lightweight kernel and software stack
that abstract event notification/polling from hardware along with a
bit of power management code. Something that would have been to be
done *anyway*. The code is BSD licensed too conveniently enough.

It looks to have a decent standard library as well, and uses gcc for
cross compilation of applications. Perhaps this would make having an
MPU more feasible assuming that the mps430 or a similar chip is to be
used and that the backend port to it is complete enough.
