Beach Bee Rooters in the NAS Network

Originally the rule was that every beach bee rooter in the nas must talk directly to every other one. That way you can't have loops in the information, because it can only comefrom the source. So there are solutions to get around the limitation. This, i think, illustrates a general principle where we have all these great protocols like dans and bp that help our applications discover things but at some point something can't be discovered. It has to know where stuff is, right? Ok?
