Very true.  I guess I presumed, quite incorrectly, that kernels map
uniquely to hosts.

On the other hand, ethernet numbers are unique, which is rumoured, if
I heard correctly, to be used by unscrupulous software suppliers and
web administrators to log the browsing activities of unsuspecting
visitors.  So one may attach one or more ethernet numbers to an arbitrary
string and get some additional degree of uniqueness.

But without a registry, no uniqueness can be guaranteed :-(
