You could also use the `org-property-set-functions-alist' trick with the
:ID: property. If you added an "ID" entry to that alist, Org's usual
automatic id creation would be unaffected, but if you set ID manually,
you could write a function that would first prompt for your
human-readable string, then check for ID uniqueness and append random
characters to your string until it was unique. I think that would be a
nice addition to org-id.el.
