As previously discussed in this thread, your terminology is obsolete - the
IESG axed the use of "WWUI" and you should be referring to "initiator name"
and "target name" or genericly "storage node name".  You have not made a
case for a need for these names to be globally unique.

In any case, fully qualified host names *are* globally  unique, are already
a part of the IP protocols, and can be used as part of a URL syntax to
identify storage node objects.  You keep referring to "WindowsLaptop" as the
hostname, but that's only part of the hostname.  Are you familiar with IP
hostname constructs?
