Okay.  Fubar U.  has a registered domain, fu.edu.  And in fubar.edu
they have a host, tut.fu.edu.

>down the line from fu.edu; I send them mail to ...!fu.edu!tut.edu!jrh;

Okay, tut.edu !=  tut.fu.edu.  If there is a registered tut.edu, then
it should go there.  If not, then tut.edu is not a valid host.

Okay, that should good, where is the problem.  The problem is that
proper domainizing is not being done.

Yes. it does.

The real problem is that sites do not, 1) register themselfs, and 2)
do not use the domain system properly.

And that is why everyone should be going to a tree structure for naming
hosts.
