I covered some of the "how they're used" questions in my previous email, but I realize that I didn't touch on how they're generated.  On Mac OS X, this is very simple:

jkh at hosebox-> uuidgen 
251F37CA-F68D-4083-815D-C36973E34A0D

A timestamp is one of the datum which goes into this value, helping to assure that it's always unique.
