Our old standby CP/M-68K could be used for the two requirements
you list (it can be made ROMable, and it support the USER/SUPERVISOR
memory protection).  Biggest advantage is that it has support
languages and products, and is easily customizable.

If you need TRUE real-time support, however, [multi-level task
priorities, multi-tasking, fancy intertask communication] you should
investigate pSOS (by Software Components Group, if memory serves).
It is a small (around 8k) kernal OS designed especially for embedded
applications.  I have been quite pleased with it.
