[REBOL] Re: How to generate a UUID?

I think we have slightly different models in mind. You, I think, are looking for a "prefix" unique to a machine. I was chipping in an approach to a slightly different problem: to get a unique "prefix" for an "application node" (to coin a phrase). That's a bit of an application running in one machine; but it might migrate to another; and that machine may be running more than one application, each of which needs to generate its own UUIDs. But yes, a machine-uid function (that gets the CPU model and serial for machines that support that; or the ethernet address for machines with a card; or _something_ unique) would be a big step in the right direction for both of us.
