OFFSCHED has a real time facet that puts it in the SMP real time system arena. it has other facets such as security and monitoring. If you take a look at OFFSCHED-RTOP and OFFSCHED-SECURED you will see that I can actually get information and change a system properties (very pool implementation so far, i am a bit tired...) even if this kernel is not **accessible**.
