[Opensim-dev] Global identifiers

[Dahlia Trimble]

Would it be possible to use just the UUID part and not tie it to a specific
domain? I can foresee events where a user and a business/grid/domain
owner/whatever make a decision to go separate ways and then any other
systems out there that have the global identifier referenced may not be able
to use it to contact that user. If only the UUID were used (we already use
UUIDs for many diverse applications and the context implies the specific
usage) it could be similar to a cell phone number where a user can take it
from carrier to carrier. Resolving the current user domain would need to be
worked out but several methods might be considered from a P2P network of
resolvers to one or more central authorities, and/or simply storing it in a
cache in local installations when the UUID is first used.

If we only use the UUID part then it may have some backward compatibility
with existing user UUIDs used to identify content creators.
