"Some simple algorithms can be developed that allow remote cores (other nodes) or even heterogeneous cores (different types of nodes) to be used by the program.

Does this mean blocks and GCD would allow easier cluster and cloud computing too? Or maybe use all the CPUs in a household to complete tasks?
