> Once preempt_rt is mature enough, it's hard for me to see any reason for going with something like QNX

To correct myself: except that the Linux development process is not compatible with current cerfitication standards. Despite that, it's possible that the Linux dev process is more mature and better "tracked", and just better, than what the certs actually require, so it may eventually be possible to certify it somehow. (Anyone with thoughts on this, please pipe up...) I get the impression that some preempt_rt people have looked into this.
