I just received the latest Linux Journal that has the article about the use of RTLinux with the control of magnetic bearings. I've just started reading it so I don't know all the details yet but it still looks very promising. I don't think the adding of preempt-RT patch to the kernel will hurt anything. In fact I think it may even help out the RTAI and friends. Anyway, as it has been stated, this discussion has started too early.
