The sibling of node public-domain, and the worse one: a placement is three facts declared together, so an invocation that said none of them took all three away — the endpoint every other machine dials, the site, and the hub. A mesh whose hub was placed that way has no paths left, at the moment somebody was trying to look at it. --nothing keeps the real case (a machine that roams and opens every path itself) sayable, by name.
