RTAI is actually an extension to the kernel containing - a hard RT kernel controlling the (complete/necessary) hardware and scheduling RT-tasks - an API for RT communication (pipes, etc.) - and the glue so that the kernel runs a the lowest priority RT-task on top of the RT kernel ADEOS seems to me to be another RT kernel. Basically one couls also run *BSD on top of an RT kernel - it is somewhat just a "new" architecture (as the RT-kernel controls the hardware and the kernel must use RT-kernel API calls to access the hardware).
