It's a microkernel with even the drivers running in userspace, and has its own graphics stack. Seems the ideal setting to go for realtime requirements for the UI. I don't know if they've done anything in that direction but it seems the most well positioned to fulfill the requirements jacquesm was hoping for.

If they can see it through then that's a pretty good development. But there is more to QnX than just 'realtime' and 'microkernel', their whole philosophy about how a cluster of machines should work, the services location and so on is very well thought out. I'd be happier if Redox took some more lessons from Erlang and QnX on board than to do a re-invention. We have a lot of knowledge about systems like that lying around and re-inventing the wheel is fun but also ultimately will lead to having to re-learn those lessons the hard way.

Perhaps you should lend a hand then? :)
