[Opensim-dev] Global identifiers

[Karen Palen]

In that case I would suggest using a type 1 UUID (based on MAC address and
time stamp) rather than the type 4 (completely random) that is normally
used.

http://en.wikipedia.org/wiki/Universally_unique_identifier

This would provide a cross check and measure of authentication. If nothing
else a central repository would then have large numbers of UUIDs that could
be traced back to a specific machine an date/time.

For many purposes this traceability is undesirable, but as an authenticator
for attribution it could be a valuable asset.

It is certainly spoof-able, but it would provide an extra layer of checking.
