There was a paper on something like this in Operating Systems Review
about a year ago. The system was called AAMP (I think) and was written
by someone from Sequent. The system arranged resource management in a
heirarchical structure, with the root actually managing memory and I/O.
Client operating systems perform basic I/O functions by passing messages
to its immediate server, and on up the tree. A server has access to the
memory spaces of its clients, which facilitates message passing and
allows for easy debugging of client operating systems.
The example system was a Sequent Symmetry running several copies of
a modified Dynix but the paper made its point that a heterogeneous,
multi-OS multiprocessor is possible.
