MarkM, where you at GMU when that visiting archeologist presented a talk
about the "Origins of Writing"? Or, are others aware of this
finding/theory? It's a fascinating story of the use of tokens for
inventory or sales accounting; apparently for security reasons, such tokens
were eventually placed in secure envelopes, but eventually for identity's
(credential's?) sake, they were first stamped on the outside of the wet
clay envelopes, hence inspiring "writing". This was done several thousand B.C.
I've always wanted a more modern version of that "clever hardware" for carrying credentials/capabilities/whatever.
just a naive thought,
