That approach, and others that might be dreamed up, can generate IDs that
are either guaranteed to be unique, or are extremely unlikely to be
nonunique.

What I was hoping to find was a way of creating a unique ID that was
verifiably one-to-one with the subject entity, and hence (presumably)
unique.  For such a purpose, the uniqueness would not have to be absolutely
infallible to still be quite useful.  In other words, the absolute
uniqueness was somewhat less important than a repeatable and confirmable
correlation with the subject.
