Hi Bhushit,

I think EL/IX can serve both the embedded and RT world.  In many cases,
as you say yourself the line can be blurred.  I feel it should be
possible for deterministic hard real-time OS's to provide a method to
conform to at least a subset of the EL/IX specification.  

For these reasons, I think this list is an appropriate place to discuss
the API for all systems seeking to provide some level of compliance,
including RT systems.
