Re: [ietf-provreg] Unique identifiers for Contact

[Rick Wesson <wessorh@ar.com>]

Pick a namespace for all your contacts, such as FLAME-?????-CT anything
created with that prefix is yours, the likely hood of others creating
contacts within your space seems unlikely.

the handlespace is 16 chars wide (it think) and should have plenty
of unused names.
