If you have a point-to-point communication method, in a network of N members, each member have to use (N-1) communicators and each member should be independently wired with all the other members. That means (N^2-N)/2 wires which is unpractical. This is the biggets practical problem with quantum communication. Concerning the KLJN crypto system, the problem is solved and now it is network ready. It can distribute an N-bit long secret key in one KLJN clock step (2 steps with re-initialization) throught the whole network. It is using a KLJN network and a parallel regular network.
