Is physical isolation of the system really a requirement? AFAIK DO-178B
explicitly allows for software partitioning. (I.e. suppose I had a kernel
that can provide -say- an Ada runtime system and a Linux environment
in the same physical machine, protected from each other by the MMU, and
I could prove that there is no way for those systems to interfere.)
I'd be interested to hear what people in this NG would would think
about something like that.
