Well let's speak of triplicate names:

The name zeus is used for three sites in New Jersey, Oregon, and Great
Britain.

I am getting a bit tired of adding -dxyz!non_singleton_offender to
pathalias's makefile.  Someday soon the command string will be too long
to pass into the shell from make.  One solution would be to modify
pathalias to accept a dot in site identifiers but just output only the
sitename before the dot (easy), AND modify all the non-singleton names
in mod.map.uucp to the full domains (harder-best done once via
cbosgd!map and its volunteers).  I still wonder why the maps aren't
adequately check for non-singletons before they are sent out, a simple
script would show a small set of likely candidates.

For example:
		produces:

zeus.OR.UUCP		x(DEMAND)
		x!zeus
zeus.NJ.ATT.UUCP	y(DEMAND)
		y!zeus
zeus.HWCS.GB.UUCP	z(DEMAND)
		z!zeus

We could still have just:

ihnp4	x(DEMAND), zeus.NJ.ATT.UUCP(DEMAND),  ....
		ihnp4!x
		ihnp4!zeus

for now, and switch all of the database over to domains with time.

The major problem (and possibly advantage) of Usenet is that random
additions to the network take place. No naming scheme will allow
addresses to remain fixed if anyone is allowed to add any host name to
a network at will. Some governing body must allocate names if order is
to be maintained. If people do not want to have some central network
operations center, than chaos will be a fact of life.
