Out of curiosity I had a look at the mentioned RFC and found that there
is a (suggested) registration authority

  http://www.itu.int/ITU-T/asn1/uuid.html

They can generate a UUID for you and in case you think it necessary you can
also register it.
While ITU seems mainly concerned with ASN1 object identifiers, might it
not be advisable to register Jeff's UUIDs as OIDs anyway, perhaps for
future use in SNMP MIBs?
