The advantage to couple Isolates with a shared memory area is about the 
same as
providing a messaging facility between them: You can move data from one
Isolate to the other. A shared memory area seems like the most efficient 
way to do
this between Isolates and even between different VMs on the same host or 
cluster.

This could be similar in use to the Object Oriented MPI (OOMPI)
(http://www.osl.iu.edu/research/oompi/).
