Sometimes.  One of the unique Amiga things....
Of course, ALL programs share the same "address space" if I'm understanding you
correctly :)

Well, I don't know about commercial packages, but my Jazzbench program is
a *group* of co-operating processes.  Base package requires four.  And it
usually works.  Usually.  Not bad for a package written without a knowledge of
what a semaphore is...

Under 1.3 it was a lot easier to insert GetMsg()s somewhere in your 
ray-tracing package.  Under 2.0 I would not be surprised if such things became
more prolific (that is multi-threaded packages).
