I don't see where you will need such a communication layer. IMHO, the 
proposal is restricted to one process only. I think that going further 
is out of the scope of the project (if you are interested in parallelism 
inter process/, you maybe you can see HPX.

I don't know OpenMP :(

Could you elaborate?
