The thing that I am worried about is that if you/we dump a whole lot of time into moving Lv2 to preempt, we would never have the brain power to even start Lv3. Xenomai seems a reasonable choice, but I do not know how much a moving target it is... Also, there has been enough efforts to get preempt working that it might not be a huge thing to get Lv2 really working, but we really need to look at homw much effort it will be to get it into the current code base compared to starting clean.
