I'm not sure what you mean exactly. Once you have a system of software running over multiple computers on a network you will have to copy data to other computers and treat everything as not just an asynchronous node, but a somewhat unreliable node as well. I think this is a given, but I don't think software architecture is very well solidified on how to scale large programs even within the same process.
