This looks very interesting. I need to read more into RTAI and friends
when I get a chance. 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.
