------------------------------------------
You could also use the Preferences system to store a random permanent node ID.

> CASSANDRA-2027 creates the need to generate type 1 UUIDs using arbitrary
> date/times. IMO, this would be a good opportunity to replace
> o.a.c.utils.UUIDGen with the class that Gary Dusbabek wrote for Flewton
> (https://github.com/flewton/flewton/blob/master/src/com/rackspace/flewton/util/UUIDGen.java),
> which is better/more comprehensive. We can even eliminate the dependency on
> JUG.
> Patches to follow.
