Interesting analogy. When I was told about this many years ago, it was described as the 'n factorial problem'. This problem assumes that directionality of the communication is important. If you have two nodes, they are 2! ways to communicate. If you have three things, there are 3! or 6 ways to communicate between the nodes. The suggested solution was similar, group components together behind a black box facade so that 30 components can be reduced to 3! main communication paths or less.
