One could use message passing for all communication in such a system, but a hybrid approach might be best for this architecture, with use of shared memory within each box and message passing between.  Of course the best choice depends strongly on the particular task.

OCaml code should be able to share immutable OCaml data with other processes just as it shares libraries.
See http://cap-lore.com/Software/pch.html .
Some of the ideas there might be improved with hardware support.
