Non sequitur.
Mobile root DNS servers are what is insane, because the queries must
terminate somewhere, and ultimately there must be something that
doesn't have a circular dependency -- requiring working DNS to get
DNS.
As for using DNS to manage frequently changing locations of mobile hosts,
DNS is almost perfect for that -- it's just the sort of thing DNS is
designed for,
depending on how frequent you mean by "frequently changing".
