We are hoping to develop a Hard Real Time Operating System in Ada for
use in a distributed system. We would like to have separate Ada
executables for each 'application' running on the processor, with
controls to ensure that the 'applications' do not access each other,
without using calls to the RTOS.

Does anyone have any experience of running multiple Ada run time 
systems in the same environment ? Is there any good literature which 
details how the Ada run time system works, or is it entirely compiler 
specific ?

So far RTOS's like RTEMS appear to require you to link together all 
of the S/W for each node. This is not acceptable for our system where 
we would like to dynamically allocate 'applications' around the 
system according to resource availability.

Any thoughts would be appreciated.
