UUID's aren't intended to be cryptographically strong.
They're intended to be fixed-size identifiers that can be created
in a distributed manner such that if nobody "cheats" then uniqueness
is preserved. I believe the reference code (in an old expired I-D)
hashed the IP and/or MAC address into the entropy.
The local time (in UTC++ :) is also there.
